Endo Speed 4 being great and we are waiting for the Deviate Nitro 3 and the Superblast 2. Competition will be rough this year 🎉

I can tell based on the color of the shoe when Kofuzi bought the shoe with his own money :-)

I do miss your videos along the waterfront in Chicago 🏙️

After trying nike, adidas, hoka, asics, brooks I finally found my ideal shoe in these. Super comfortable, nylon is more forgiving than carbon but still responsive, very stable unlike most of the faster foams and can serve a ridiculous range of paces from easy runs to intervals. AMAZING SHOE.

I've had all versions of the SES and I am a fan for life. This model of shoe just works - Saucony really hit it out of the park with the versatility of this shoe from easy pace to race day (and I have worn it for all of the above). This shoe is magic, and has been my preferred go-to for the past few years. It is ALWAYS in my rotation.

Saucony has been putting out some amazing shoes... especially the Endorphin line! Looking forward to watching this and then trying a pair soon. Let's do this....

Great review Mike! I’m still on the speed 2’s. I F’d around and watched too many Kofuzi videos and bought too many shoes in 2023, without having the mileage to support it. 🤣🤣 So now will run through all these various and wonderful 10 pairs before even thinking about the NEXT rotation 😂🙏

Another awesome review! Love the addition of the running footage with audio of the ‘slap slap slap’ as you talk about how it feels to run in. 👌

I enjoy the Speed 4 more than the 3 as the 3 caused lateral foot pain for me. No issues yet with the 4. Did a 10K race on Saturday and will be doing a half marathon this weekend in them.

Can I just say how incredible the B-roll shot of the shoe at 0:27 is?! Non-elite runner maybe but top tier videography!

Wild how I've enjoyed every version of the speeds and looking forward to a new pair of speed 4s for the summer

I’m still using a pair of Speed 2s and love them.

I've been looking for a racer for months, and gone down more rabbit holes than I can count. Thanks so much for your help in sorting through the clutter I went with the Pumas, and found them on sale to boot

Kofuzi, you have been doing these reviews for many years now. You have always been by favorite running KZfaqr.

For one, I’m glad that the speed 4 is not safe like the speed 3. I like it that it’s gone back to its original intent

I was the same way with the speed 3’s. After about 2 mile my right foot would get a pain in the ball. Now with the speed 4’s I’ve had no problems.

Jacket is definitely jacket of the year 🤩

Wow! That intro said it all how good this shoe! 😳😮😲

I tried these. While I may pick up the Runshield version when that comes out, I sent 'em back and picked up a discounted pair of ES3s as a backup to my current ones. I love that shoe.

I really enjoy these. Got a bit of a lockdown issue with Saucony, but these seems to work well. They handle all paces well, but they make me want to push it a bit. Really good looking top, I have the black colorway.

Great Review Mr Kofuzi, surely one to compliment my Puma Deviate Nitro 2.

Thanks, great review! I got the S4, though I'm really eager to check the upcoming Deviate Nitro 3 & Superblast 2🤘

I love this shoe! I’ve taken out for a couple workouts and it has felt great! It’s a perfect blend between the 2 and the 3 for me.

Looks like Saucony and Ascis will reign this year!

I've done 55km so far. Four 10km runs and a 15km. I agree with pretty much everything regarding the ride of the shoe, especially the shoe feeling better at faster paces. Where I differ is on the upper. I think it's one of the best in recent memory. The tongue especially is a fantastic design with it being relatively long and having the padding at the top. It just feels great sitting on my foot/ankle and unlike most shoes, allows for comfortable lace locking of the shoe. The upper is just so pleasant to be in and is a breath of fresh air compared to other super trainers or whatever you want to call them. I much prefer the upper to the Deviate Nitro 2 which feels a little scratchy and the seams can be felt. The only thing about the upper I can really fault is the stretchy laces which can be switched out.

great review, just purchased Saucony Endorphin Speed 4 Pro and planning on dominating cherry blossom 5km on 06Apr2024!! tested shoe on treadmill and i was booking at 5:56 min/mile pace. They felt really nice and springy!! Woohoo!!

Good morning. !!! Saucony for ever!!!!. Like to Kofuzi. Have a great day.

Great review as always! I was waiting for your thoughts on this shoe! I will finish on a pair of threes and i will wait for new color ways but definitely grabbing a pair of this.

Just found your channel and am quickly becoming a fan of your show reviews!

Definitely, love the speed 4 series since the ride was effortless and nylon plate adding the stability to shoes. Could be the best shoes atm but hoping for after 100 miles video on this shoe from you

Love that you bought it yourself! I think that is so important as a consumer who watches shoe reviews. BTW…the Puma Deviate Nitro 2 is at Marshall’s (discount retailer in So Cal), for $40. Bought 3 pairs. I’m keeping 2 & selling 1.

Endorphin pro 4 review when!? Looking forward to that one

Great video! I’ll put in the Adidas Boston 12 as a good alternative to these Saucony Endorphin Speed 4 as well… from a usage-case but more for the price since you can get these on discounts already.

Just joined the Saucony family! Coming from hoka. Ended up with the guide 17s and they feel fantastic! Best I have tried on in a long time where both actually fit great. Usually deal with tight shoe fitting tighter. Looking forward to get more Saucony in the future!

A true lover of sports running

I am almost the opposite with the speed 3. I really didn’t like it that much when I first started running in it, but over time I have grown to enjoy running in this shoe. It does seem to work for me. I will probably be picking up another pair at some point.

Was hoping Saucony would drop the bomb and give the Tempus 2 a plate to be the first ever stability Racer. But it seems like its coming at the end of the year with hardly any upgrades aside from an updated upper.

I like the comfort improvements for everyday running but for race day I would prefer the 3 to this one.

I’m an amateur runner looking for fast running shoes (10K/HM/FM) but do not wanna break the bank for a super racing shoe. Should I get the endo speed 4 or ASICS magic speed 4?

I agree with all your points here, Kofuzi. I found the shoe very clunky at easy paces, but the moment you start to run with more effort/power, it comes alive and wants to stay there. It made me think of a firmer Pro 3 if you tried to make it more durable/a daily trainer. For me, it's a bit too firm for the full, but I can see myself using it for a half. I love using it for any higher effort workouts.

I really love these shoes, coming from Hoka and Nike.. I will probably add a pro 3 or 4 soon.

@Kofuzi Just a little heads up for your viewers, the Devi8 Nitro 2s are starting to show up at your local Ross for $39.99! I scored a pair for that price last week and I absolutely love that shoe! They’re also selling the Magnify Nitro 2 and Fast R for the same price if you can find them in your size…👍

Best super trainer out right now, period. Fixed everything that was “wrong” with the 3 but the tongue is still a little disappointing. I wish their trail shoes were as good. This laughs at shoes like the Mach X and the Boston 12. I’m kinda surprised you said that about the upper,lower because I felt like I was swimming in the Speed 3 upper and this feels like it’s dialed in much more.

As a Endorphin speed 1/2/3 user I'm really enjoying the Boston 12. Not sure why it took me so long to try Adidas but Pro 3 and Boston 12 have replaced the Endorphin Pro/Speed combo for me. 6mm drop and foam just works a bit better for me. Also really like shoes on sale. :D

There's an entire psychology of running you could put to the test here. Maybe a more exciting colorway might have produced a livelier result? ES4 comes in some really nice ones. But then again, you picked this colorway yourself so 🤷‍♀. I'm not sure this fits in my rotation because I've always seen ES as a speed day shoe, and my speed day shoe of choice is TS9. Still. Glad this one didn't leave you in crippling pain!

Just found this video, despite it not being super-new. And I agree with you on the upper. I bought the REI colorway, and while it’s kinda cool, it doesn’t look like a speedy shoe. It looks, well, pedestrian.

Agree with everything you said. My favorite out of all of the Endorphin Speeds has been the 3. I don’t mind the bit more stability in the 4 but the upper just doesn’t work for me. I can’t pinpoint what it is but no matter what insoles I try it still feels a bit sloppy on my foot.

Heels issues are a tricky thing...too much heel lockdown and the achilles people get blisters/rubbing. Not enough, and the flat heel profile people get heel lift which results in heel blisters. Which is made worse by really hard heel cups. The Endo Speed 3 upper and laces were way too stretchy which only made heel lockdowns worse. It got to the point that I couldn't trust the shoe for any run longer than 12-15km, anything with big pace changes or elevation changes. It basically became a over priced daily trainer which can handle strides. I moved on to the Novablast V3, which has way more versatility and a heel that is fabulous, for me. And the NB V4 just seems like they tamed it a bit too much.

Love the speed 2’s, couldn’t get along with the speed 3 (tried them in the store and just felt flat and unlively to me), tried the 4’s and right away I was like “yeah this is the shoe.” Looking forward to getting a pair and hopefully try out the Deviate Nitro 2 at some point!

first time i wore the es3 it feld identical to first time i ran in vaporfly 2

I loved the endorphin speed 2 and the pro 3 and I do all my long runs in the puma deviate nitro 2. I should have a look at this ;)

Glad this is turning out to be so solid. I still have my Speed 3s and they never fail me. Had high hopes for the 4 and looks like this needs to be added to my lineup in the future.

Loved all 3 previous Speed models, with the 3 my favorite. Looking forward to getting this on my foot later this summer!

I took my Speed 3 to over 400 miles, solid shoe! I also could not agree more on your comment about Triumph 20 comment about it being a workhorse. I also took these to over 400 miles and just bought another pair at a discounted price. I couldn’t find any retailer selling Speed 3 however

I love the nylon way more than the carbon, The speed is my fave, I always feel light in them and for a bigger runner that says a lot.

8mm of stack in the front sounds cray cray 🤯

There's a budget friendly running shoes from saucony called tide 2 kinda looks like the speed 4

Great review. I still don’t know how to feel about endorphin speed 4. The speed 2 was godly. The 3 had the most slippery outsole I’ve ever experienced. It was also boring to run in.

Oeh, that's one gorgeous looking Pro 4! Much better than the white/orange ones.

The London red colorway for this shoe is amazing

I had issues with the Endorphin Pro 3, over the 10 k I suffered a big pain in my foot. I loved the Pro 2, let’s see the pro 4. But the Endorphin Speed are absolutely my favourite from the 2 to the 4 now 😄

Still rocking the Endorphin 1 (and Pro 1) for big workouts or races haha! Look forward to updating to this model, ir maybe the 5 if I hold out long enough lol

Love that color way! I’m trying to love this shoe. It’s firm for me. I love the light weight and I tend to run fast in it. I’m just dealing with some sore ankles and knees in longer distances. I’m 46, 210lbs and wear a 12.5 so I’ve been chalking it up to being an older-bigger runner. I’ve been wearing a NB SCTv2 which isn’t quite as fast or light but provides more cushion.

I picked up a pair of the Deviate Nitro 2’s for $40 at a Burlington Factory Outlet a couple of weeks ago!

Tale a look at the REI edition of it...probably the better looking one so far

The toe box tapers even more aggressively than before, had to send mine back for the sake of preserving my pinkies. Agree with you that the upper is overbuilt for a “speed shoe”. The Pro 4 upper works better for me.

Had all 3 prior versions but not pulling the trigger on this one just yet. Going to wait for the puma deviate nitro 3 first.

I haven’t tried since the kinvaras but tempting to go try saucony again

cant wait for endorphin elite 2

Nice colorway 🔥

The Speed 4 is a step backwards from the Speed 3. The Speed 3 upper has a far superior fit. Something in the 4 feels off with how the foot sits on top of the sockliner. Saucony could've saved some weight if they didn't add a big chunk of foam in the heel.

Im having the opposite problem between the 3's and 4's. I am getting hot spots in my 4's on the pads of my feet. I am wondering of the forefoot has more stretch and I need to tighten up my toe box..??..

I’ll agree that this shoe is better at faster runs, but for a different reason. For me when I run slower I need more support, so I prefer shoes like the pjs if I’m going slower. However i did a recentfartlek in them and my pace was great.

Great review! I've started running two months ago and I'm about to buy my first pair of running shoes but I can't decide myself between the Boston 12s and the Endorphin speed 4s because my wallet can only afford one pair at the moment so I'm looking for a versatile one to lower my 56 minutes in 10k. So what would you suggest me?

*Checks date* - nope, not April 1st. Great review, Ko, I'll be adding this when my Sp3 dies.

Upper looks a bit reminiscent of the Triumph 17. It does look a bit 5 years ago! I have the 3a (Speed and Pro), and the Triumph 20, so will try it anyway when due to replace.

They need to start retroing these like Jordan’s cuz I need endorphin speed 1’s back in my life

I know that you ran the downhill course in Washington State a few years ago and I'm running that same course in September (marathon) I'm considering the Endorphin Speed 4 or the Puma Deviate Nitro 3. With the mild downhill on gravel surface, which one would you consider lacing up for that race choosing between the two? I appreciate any thoughts our input.

I loved it on a tempo run but when I ran a slower recovery run yesterday I found the shoe to be too stiff and not as enjoyable as previous versions. I wonder if it will become less stiff overtime.

6:21 Kofuzi: Grey shoes always feel a bit sloppy to me also Kofuzi: buy a grey pair of Endorphin Speed 4🤔🤔🤔

Due to some posterior tibial tendinitis from over working I had to switch to the Saucony tempus but I’ve been getting back over to the Speeds and forgot how much I loved them

definitely thought you'd compare it to the Boston 12. I love both and wish I could merge them together.

I have couple of pairs of endorphine speed 5. and it is my shoe of the decade. I’m sure most of you will be very excited 😊

Describing an upper as ‘frumpy’ is fkn insane 😂

I don't have the Speed 4 but just went out for a run in the Pro 4 yesterday. Although the upper of the Pro 4 are quite comfortable, I do feel that it could use a little bit more structure to make it feel more racing shoe-ish. Not sure if that is the experiences you are having here or with the Pro 4. Looking forward to your take on those.

Ko, do you know where the HG is located in the midsole of the pro 4? No one seems to know and some people are saying it’s only the back of the heel.

guys i think he might like this shoe

first glance of the upper... reminds me of my brooks ghost 14 in the grey colorway 😅

Great review, Mike! I went with the TYR speedworks! I hope its the right choice. Yikes!

Love these shoes

I've really been enjoying the Topo Cyclone 2. Sounds similar, but has no plate of any kind. I like the lower stack 28/23 for more stability.

My take is, design is absolutely elite, looks fantastic regardless of colorway. Same for Pro 4, and NB Rebel 4 and new Elite. First shoes ever you can say that about?

Endorphin Pro 4 review coming soon? Been waiting eagerly!

Gotta have 2 pairs of Saucony Endorphin Speed 4, Asics Novablast 4, and Superblast 2..

Good evening from Bangkok, Thailand

Very happy the 4 doesn’t give me the hotspot 3 did. Agree it does “easy” worse than its predecessor and I found the upper much more snug in the toe box but this is a fantastic workout shoe overall.

Looks like a shoe you could mow the yard in while drinking a Bud Light.

Love it! Just bought the version 4 myself. Used them 4 times and they are OUTSTANDING! Question: How many miles/km do you think you can run in them before you need to by a new pair of running shoes? It's because I've bought them with the purpose of using them as the only running shoe since they are so versatile.

Love your videos as always:) Who makes the black jacket??

Time to end the black balling, Saucony. Send this man shoes!
