I usually wear a 10.5 in boots but had to go up to 11 with these. Now that my toes have room, I can wear these comfortably. The craftmanship is top notch. They don't seem to require a break in, but I am trying to "wear" them in a bit so they conform to my own foot more. I might change the laces (these tend to come untied); maybe I'll switch the insoles at some point. I imagine these are going to be with me for a long time to come; if I have updates, I'll add them later.
