The bone on top of my right foot is a little higher than normal, though my left foot is normal. A lot of shoes that have a top strap design dont work for me cause of this, also my chemo treatments made my foot a little bigger. Id grab shoes in a 9.5-10 prior, now 10 is the minimum but just get a 10.5 for a little more comfort. The 11 was perf for me in these, the 10.5 like I said woudve been fine after a but if wear but I aint trippin over a half size. Cats always argue about sizing like a half size up or whatever ever hurt anybody.
