I have had these for a week. They rock! I like being the only one in the gym with barefoot shoes. I had the spyridians for a year... then thumb toe at seems busted out. I do a lot of plyometrics... so a year isn't bad... these may be better. I got the tactical black... don't need any more attention...kc city isn't ready for these in the gym... their a bit old fashion out here. Everyone does straight sets...no circuit training....only the cross fitters out here may appreciate these quality shoes...im neither...but know quality.
