My first pair of Tevas, I love them!! So comfortable. First day on I wore them on a long bike ride and 2mi walk/hike. No blisters! At first I was worried because they were rubbing my pinky toes a bit, but it was totally fine. I'm a true 8.5 in almost all shoes, and read a lot of conflicting reviews on whether to go up or down in size... I would recommend just ordering both if you're not sure and try them out. Personally, the 8 is perfect on me... like I said, I'm a true 8.5 with average width feet / length of toes. Both straps are adjustable too so you can "customize" the fit.
