These sandals are SO comfortable! They fit great, and even though they have no heel strap they stay right on my feet, even during long walks. A lot of people say that Keen sizing runs weird, but I don't have that experience. I purchased another pair of sandals in an 8.5 based on other people's reviews, but was disappointed because they were too big. I wear size 8 in every shoe I own (never even 1/2 size up or down) and Keen 8 is good for me.

Definitely buy these sandals if you're considering them; you won't be disappointed.
