These shoes are very comfortable. When I first put them on I wasn't sure. They felt a little wobbly. But after a few days they break in well. The only problem is that since they are very light and weigh next to nothing, they won't last for many years. But that's ok as they are not too expensive. The skin is thin, the sole is light. I want Merrell to make a winter version of this shoe. Without perforation, possibly lined.
