I bought these less than a week ago while out looking for a classic running shoe. I spotted these out of the corner of my eye and noted that they looked like an enclosed rafting shoe which is precisely what I wanted for my job. I work in a hospital emergency department and I needed something breathable but with the support of a shoe. I purchased an other pair of Merrells months ago and loved how, unlike many shoes I have tried in the past, there is room for my little pinky toe. I was concerned about the minimalist drop in the Proterra for long periods of standing, but I decided to try them anyway and it was the best choice I have made in foot wear thus far. They are the most comfortable shoe I have ever worn. I rarely wear any other shoe any more, I even opt for these over the running shoes I went to buy. The support is unmatched and the breath-ability makes it comfortable to even wear these without socks.
