They run small. If you buy work boots, you know to get a size smaller, they usually run a little big. These don't, the run small. So I buy a size10 work boot, I tried it on, seemed tight, I figured it would break in. Not the case, it got worse, my feet seemed like they are being forced forced twards the routeof the boot, and the composite toe edge is rubbing on top of my foot. If they offered a 10 and a half, I would buy those. But they don't. They could have been a great pair of boots.
