NW is always true to size, this pumps once you try it on feels ok in your size, but after you break the shoe it will defin.fall of while you walking, inserts can help or go 1/2 size down, it won't hurt your toes because of the structure of the shoe top. this is the 3rd pair that i'm ordering and returnig due to defect that pump has, cheaply made but look fantastic, very comfortable, walkable, good for the price, i'm returnig for another pair, hope i have a luck to get without a defect.
