Black and white platform sneakers - Nike Court Vision Alta. Worn 2-3 times. They are comfortable. I have a zillion pair of shoes and I'm just finding I don't reach for these very often. Street fashion meets b-ball authenticity in the distinctly modern Nike Court Vision Alta sneaker built with a collapsible heel for added versatility. Crafted from synthetic leather with a chic tumbled texture above transparent mesh, this airy sneaker offers foam-cushioned comfort while keeping its heritage hoops aesthetic.
