I don’t know what version of the Reebok CrossFit’s I had prior to purchasing this pair, but these are just as good. Straight out of the box I was able to put them on and go for a run. Amazing grip on the soles and they look great. Haven’t had any issue with the shoes as yet.
I’ve never owned a pair of Reebok nanos, however I’m impressed by the stability and width of the toe box featured in the shoe. Having been an Olympic Weightlifting enthusiast for many years, you could certainly use these shoes for Weightlifting-heavy WODS, squatting, etc.
