These shoes have nearly 2 inches of nitrogen infused supercritical foam with a 9mm drop. What that actually means is that they are incredibly comfortable and bounce you forward with every step. Even with the outrageous midsole stack height, the shoes are stable and supportive - easy walk or stand all-day comfort. The upper is mesh with enough padding in the right places. The clever overlays add support and look so cool. The tongue is thin and a little narrow, but the padding around the eyestay means there's zero lace irritation. I'd buy more if my Wife would let me!
