GO BY THE SIZING CHART LISTED!! I am a woman that usually wears an 8.5, and ordered a size 8. I wear heel inserts and 2 pairs of socks with mine because they ended up being a little big. Great boot, light sole, good grip, with excellent ankle support. Bought these for a 5 night hike I have planned and will update my review once I've completed that, but so far these boots have been great on shorter hikes with lots of vertical climbing.
