I have high arches. I normally wear XP PROs which are much sturdier than these. But i wanted something soft to alternate with thru the week. These are made of the same material as the industrial floor mats for workers. Theyre soft but have a lot of density and support! I was so happy i bought these that i bought a second pair! My only complaint is that they make my feet sweat even with the airing slots. Other than that they're everything i want in a work shoe
