“I was playing Pickleball 5-6 times a week both inside and outside. I started to experience heel pain, Something I’ve never had in my life. I was icing my heels every day. I saw an ad for gravity defy in a magazine and decided to take a chance on them solving my heel issue. I initially purchased a pair of Mateem shoes and my heel problems went away rapidly. I have purchased 6 pairs in 3 1/2 years. It is my opinion they would last nearly forever if you play inside on wood surfaces, but outside on concrete, they wear faster.”
