I returned these right away. The straps are arranged so you can tighten the one across the toes by pulling on the one by the ankle. Well, by the time I even got it close to tight, the large, plastic, bulky adjustment piece ended up in the middle of my foot. Not only was this painful and awkward, there is also a plasticy connection piece by the ankle that would rub. The base is too heavy for the sturdiness of the upper straps, and it was too wide and too long for me over all. (I'm a 10-10.5 M normally, and the 10 M was too big).
