Not as good as the core 1's - Viktos Core 2 Tiger Stripe Shoe - Men's

I have had 4 pairs of the old Core PTXF in Nightfall and Spartan. (Have 3 pairs still that i rotate) I have these Core 2 in Tigerstripe now and almost never wear them. The material is way more rigid and stiff than the PTXF'S. They have significantly less flexibility and give than the XF's. The tongue is especially stiff and are constantly jabbing the crease wrar the shin and foot meet. Skip these and get the newer Core Gym's (not tried yet but seem more like the old ones). These do seem like the are built of more sturdy materials and the tiger stripe looks good, but comfort and mobility come first.
