I just got a pair because they were $50 at rebel and they had my size. Did I menition they were $50 and I had a $40 gift card to use and my old Tevas are far too heavy to run on trails and, oh yes they were $50.

Has anyone else used them to or knows someone that has used them and if so what did they think of them?

Initial impressions are they feel very flexible and very light, not much support in them at all. They are apparently meant for doing water sports and what ever you get your feet wet doing as well as being a hiking shoe.
