I believe I have a heel spur and plantars faciatis. I have a lot of pain the bottom of my foot and heel when I wake up or walk barefoot. I purchased these to see if they would help and so far so good! Sometimes they feel as though they’re slipping but they’re not. They can start to get a little tight and need adjusting if your feel swell too. Overall they really help relieve some stress off my foot and fit with many different types of shoes.
