The straps tighten up as you walk- but especially around your big toe. They strangle your big toe. Plus I have to take the time to sit and adjust the straps every time I put them on (b/c they tightened up some much from the last wear). Its more trouble than putting on socks and tennis shoes. One reviewer said to just not put your toe in the toe strap to avoid the strangle. It does work but makes them very uncomfortable to wear for more than a quick 10 min walk. Worst $70 Ive spent. I don't recommend.
