I love these shoes, have had them for a year now. I use them once a week for heavy squats. Not only was I bragging about the record, I maxed out my squat to 565 pounds and had minimal wear and tear in a year. I'm starting to notice cracks in the sole in the heel and the insole starts to slide up after a few sets, but I suspect that's to be expected after 1 year of regular use.
