Great sandals. They are adjustable in three places: over the for-foot, over the ankle, and the back of the foot above the heel. Construction is rugged and tough. Ankle strap has a quick release clip, so I do not have to un-velcro and re-velcro. The straps are cushioned underneath, where they touch the foot, so there is no chaffing or blisters, no rubbed skin at all, even on the very first wear. The best part is the sole and foot bed. Incredibly comfortable, it feels like a tiny bounce when I run, but still very supportive. I feel as if I retain much of the muscle movement possible when barefoot, but with a cushioned sole beneath me.
These work particularly well for me since, due to a medical condition, one foot is taller near the for-foot/ball. I can adjust each sandal to fit each foot perfectly.
