I bought these for a golf tournament I was supposed to be attending. I bought them in advance to wear. At first I wore them around the house for a bit. Then he went to play with them and walked around. I went through about 4 holes before I had to swap them out for my old ones. They caused a blister on my Achilles tendon. It was expected. I wore them again for another round. 9 holes punched. I now think they are on that path. I sprayed them to stretch them out a bit and played a few more rounds without getting to the 9th hole. I couldn't take them to the tournament and they still give me a blister on my tendon near the 9th hole.
