Whats underneath the Nike LeBron 21 basketball shoe? Check them out for yourself with this deep dive on court playtest, review, teardown and durability test. As a foot doctor I look at basketball shoes and basketball shoe technology a bit differently as I focus more on what foot types benefit from these shoes as well as the basketball shoe's functional attributes on the basketball court
Some of the main areas we cover in this basketball shoe shoe playtest, and performance review of the Nike LeBron 21
- The weight, durability, fit and playability
- What are the features of the insole, midsole, and outsole
- Nike basketball shoe technology explained

I ended up with 4 pairs of the 20s just because it's so comfortable & a great shoe to wear casually. I'm a bit upset they swapped the bottom loaded carbon fiber shank for a top loaded plastic shank but glad they kept the cushioning set-up of bottom loaded max heel zoom & top loaded zoom turbo.

Very much reminiscent of the 2010s era of Nike hyperdunks, design team did an awesome job of a retro feel with modern era tech. Haven’t been interested in lebrons since the 16s. These are interesting!

@ElevatingInLife 11 ай бұрын

@adamkanizsai2990 if you read my comment with proper reading comprehension, I specifically mentioned the design. It has the chunky round abouts the hyper dunk has, the lateral outrigger also is chunky and filled with rubber. You don’t see a lot of shoes going this route but instead more roundness to them IE: Jordan 38, Melo, Kyrie, the list goes on. And your vision is completely different from mine, does the world revolve around you? No, you literally could’ve just said “oh wow, this is a new perspective I didn’t think about, interesting.” But here you are, acting all high and mighty lmao.

@samhuang3339 11 ай бұрын

Great Review! I like how to quantize the shoes performance in number. But if it is possible, could you make a comparison of the performance between the main shoe and some benchmark shoes? For example, when talking about the heel height and jumping height test, you can make a colorbar and identify the numbers from the LeBron 21, gt cut, gt jump, and KD 15, which are usually under consideration simultaneously by the same style of players. Personally speaking, such a comparison would make the performance number clearer, and is helpful for the audience to make decisions to the shoes.

Please try them on first to make sure. My friend also bough a pair and had the same complaint. He said it took about 5 runs to break in. I'm to old for that. Recommend the Curry 24 Splash Jam or the Puma Scoot Pro Nitro. Super comfy. You can just put these on and ball with no break in required. Those are my type of shoe !

Idk if it’s just me but my feet were sweaty playing in the 21s. My feet never sweated in the 20s and even the 19s. I have pairs of his shoes from 15s-21. From the 15s-20s from my experience my feet never sweated or got sweaty hooping until I started wearing the 21s not sure why. And I’ll say the most breathable ones for me personally were the 15s 17s and 19s. I’ve bought two pairs of the 21s they are very comfortable, good traction and durable. But my only issue is the shoe not being breathable as the previous ones. My feet and socks were sweaty playing in the 21s but I still continue to play in them because the shoe is addicting I can’t stop wearing them even though I really don’t like how my feet sweats in them.
