Perfect fit for a size 15W foot However a friend of mine who has a slim foot, also bought them and had to return them as the straps were too baggy. THEY DONT WORK WHILE CHARGING. These are not. They are authentic MLB and the details were a nice touch. Recently, I found a pair at the Adidas Outlet that was one size smaller than that. Also, the individual compartments aren’t wide enough to accommodate a pair of shoes with more than a 2 inch or so heel. I have tried MANY different non-slip shoes over the course of a decade and these are the most reliable, easiest to clean, affordable and utilitarian shoes Ive found. I work in a hospital, so having no holes in my Crocs is a must! It works on the wireless charger and can see the light through the case.
