I play basketball in the primal 2s and they hold up, definitely capable of more than just light walking and exercise imo :) can't wait to try out the 3s!
Excellent review. I'm wondering if you know if they have improved the stitching on the outer side at the toe bend point? I've had my Primal 2's for over a year and have both left and right split there. Seems to be only glue. I had to get a 3rd party to stitch them up.
