I have the SeeYas which don't fit...they apparently run small but I didn't know this. I tried the Spirydon but didn't like how they felt. The Bikilas fit like a glove. I will run up to a half marathon distance in them and do mostly street running. Also will run my first winter with cold in them....moved north from south Texas...not sure if that should weigh in what I buy. Leary on the EVOs because the fit sounds so different than the original Bikilas. Bummed they messed with a great thing!
