So great!!!! I got a 2nd pair and my mom a pair :) However, I wear usually 8.5-9 for all my shoes, I got the 9 in my first pair and went with 9.5 in the second (this is my only pair of shoes I own this large, so these do run small) I agree it is most comfortable getting them with space in the toe as the other reviews have stated. I use these hiking, trail running and general running in Utah. For mountain use they aren't as protective as boots, obviously, for rocks but the comfort makes it worth it to me. You can feel earth beneath you in these shoes.
