I had to reorder half a size up, but once I did that, I was happy. A year ago I slipped off a wet rock while hiking and broke both wrists. After that, I did a lot of research on who made the best "grippy" soles: Vibram. I will not hike again without Vibram soles. Other post-surgical notes to self: Use hiking poles, but don't use the the straps. Stay off the rocks next to the waterfalls. Remember that clear algae is a killer.
