I have the terrible habit of pointing my feet forward when I sleep and then my plantar fasciitis flares up - numb, tingling feeling in both heels. So I was hopeful this "Soft Night Splint" would be the perfect thing to wear while sleeping.The problem is, it doesn't work. Unless you are as weak as a butterfly, it's still very easy to point your feet forward after wearing the splints because the straps aren't rigid. That defeats the entire purpose.The splint doesn't breathe and is also very hot with or without wearing socks. The base of the straps are too close to your toes so when you start to point your toes, the straps crush your toes and they become numb after a while.A soft splint is a nice idea but this one simply doesn't work. Try a rigid splint.
