"These sandals took a few days to break in. I got pretty bad blisters in the process. I then went on the Appalachian trail and found that my hiking boots were falling apart so I dawned by trusty Merrell sandals and hiked ten days of the trail (even the rollercoaster!) in these sandals. These sandals are almost as amazing as bare feet. I recommend these so highly. Get them. They are awesome. I have thin feet and they fit snugly."
