Kinda gotta get moving on some school work pronto. My shoe mileage is really confusing me. 456 for the Black Saucony Ride ISO and 408 for the Grey Saucony Ride ISO How are the black ones so far ahead? I went back a full 3 months in my calendar and the shoe cycle has been spot on it seems. Cmon, what's up with that man. My theory would be that the effect might be from my erratic shoe selection while dealing with my knee injury and ellipticalling most days.
