The top straps are adjustable so one can adjust to suit their foot. They feel very light, but well designed. So I figured I would chance it anyway and get insoles if needed. Contains 48" tape, plastic insert for tape, self adhesive clear acrylic hairline indicator & cursor and 36? Double T-Track Fence Cap. We use these from time to enable us to use a roof-top ski box or carry a canoe, and they are fine for that. It fits well around my ear and has an excellent base response. Eight months ago I spent double for Reef brand Sandals only to realize the Reef sandals were terrible once I tried these. They cleaned up with some elbow grease. The arch support seems to be just moderate. Their stuff may not always be home-runs (heck, some of their stuff dont even make it to first base), but their stuff is usually the next-best option after first-party controllers.
