Bought the fourth pair in 4 years. love these things! I have a damaged peripheral nerve from a spinal injury, so I can't feel my legs. I always have to wear something on my feet because without feeling it's easy to step on something and not feel it! I carry her to death. They look good and are comfortable which is why I keep coming back. I wear them a lot; more than one person usually... and they last about a year. They'll probably last longer, but I wear them outside or when I'm running somewhere fast, so they get wet and dirty. They probably would have lasted longer if I hadn't beat them to death. Rschunimagu
