This is a good question and I'm surprised everyone in skating likes to keep people in the dark on this. Anyway, on Edeas and maybe other modern boots you need to get a pair of calipers and find the widest point of the boot, usually around the midfoot/ball of the foot area, and figure that out. Then divide that number by half to find the center point of your boots. So on my pairs of 290 and 285 boots they both measured around 108mm, so you make a marking at 54mm and that will be center. So the outside edge of the blade should be at that center line. It's still tough without a laser level or special tool meant for Edeas, but that way gets you in the neighborhood. On both my boots center was actually about 4-5mm off from the center stitching at the toes. Another test, too, albeit imperfect, too, is the boot and blade combo being able to balance on a table without holding it. The idea being that it's centered if it can balance itself, so use both. However, if your feet have pronation or supination then you might not want a true center mount, though. Edea actually gives this advice I'm writing here on the SkatesUS site, except the table test, but ONLY for roller frames. On ice they're tight lipped, but for roller frames they say to do what I just said, and that center on the heel usually matches stitching points, but they explicitly say often the toe stitching and true center can be off by 4mm. There's another machine called the Snyder boot measuring machine, which is a jig that folds and has a line in the center, but it won't work on Edeas, only older style boots like Jackson and Riedell where the sole is the same size as the boot. I think a lot of complaints about Edeas are from wrong mounting, where techs either just line the blades up at the stitching, eyeball it, or use math calculations or measurements based on the *sole* of the boot, which on Edeas is irrelevant as the sole is much smaller than the actual boot. I got lucky with a very good Russian tech for my first pair, but my second pair I had an inexperienced tech and ended up doing the mount myself after talking to the retired Russian one about my problems.

Lilie Smart if the blade fits on the boot correctly then it’s good to mount, idk if u already did it lol. Also I usually do temporary mounts just in case it doesn’t work out

you wont die, how many screws and what ice skates/boots/blades?

@@egoist5134 haha) thank you! I have EDEA Chorus. I'm missing #2 on the right boot and #9, #10 on the left boot.

@@RoLLerHel did you get the blade with the boot or did you get someone to mount it? what website did you order them off also, maybe if you got them mounted and missing screws you should maybe email them?

@@egoist5134 I drove to the shop and got the boots and blades. They mounted it for me. I emailed them, waiting for the reply but I'm skating today :/ not sure how bad it is... Will ask the people who sharpen the skates - maybe they can help. But not sure if they have Edea screws there :( I was just trying to understand how bad this missing screws situation is. Like, can I skate?

@@RoLLerHel do your blades feel loose?

2 years in Edea? Probably time for a new boot

@@jenpw1525 If the feet are not growing anymore why she will need new skates?...

@@danitagirl Because boots break down.

@@jewlia7909 i have had my boots for 8 years but i barely skate in them and they look good as new, maybe it differs to the amount of time skated?

@@deniz6304 edeas tend to break down a lot more quickly than other brands because of the material that they’re made of. However, skating time and level do account for its breakdown too.
