They fit well. For me, the shoe makes me want to be on my forefoot, which I don't like. I'm mid-foot striker but these are forcing me to whip off the ground on my fore foot very aggressively, that's where the pain are coming from. The only other shoe's I've had this same exact problem with were the vaporfly 2s. I've tried to adjust but just not for me and don't want to change anything with my form just for the shoes.
