Just got them so here's my comment on sizing
Reviewed by Muddzy from NJ on Friday, January 26, 2018
I ordered the Akasha in 43 (10) and this Ultra Raptor in 43 & 43.5 (10.5). Normally I'm a 9.5 to 10 and I usually order a 10 since my feet are a little wide. The 43 in Ultra Raptor fit perfectly. The 43 in Akasha were too narrow. The 43.5 were still narrow but my guess is they will loosen a bit after use. Not sure which I will keep or if I will keep both. I can't comment on durability or comfort during run since I haven't used them yet. I will try to remember to update the review after I use them.
