These boots do size a little large. I am a size 7 and normally like to go one size larger in hiking shoes but 7 1/2 worked great for me. I broke them in by doing a 14 mi hike, and only got a small blister on the back of my left ankle (the moleskin I used moved down my shoe.) So these boots are primed for my hike up Mt Whitney next month. I was debating whether or not to go with my day hiking boots but decided to go with these Salomon boots to get a little more ankle support.
