I wear a size 11 on Nike, Sperry, Adidas and Vans but somehow their size 11 was too big. The sole of these shoes is literally the worst I've ever tried and it's only 3-4 steps from trying on and walking the carpet. It's too narrow and together with the soft bed I felt like I was walking on a marshmallow covered log and almost fell. Save time and money and simply buy a cheap pair of moccasins from Walmart or TJ Maxx.
