I received 2 pairs of Hailey slides today. I put 1 pair on, and felt instant relief. I actually said "Ahhhh", almost in happy tears. I have no arch, and severe pain in my left heel. Also my left foot is wider, due to ankle fracture. The left slide adapted softly, to my wider foot, with no pain. I had knee replacement on right leg. My left knee still hurts at times. Wearing these slides, has reduced my knee pain too. The slides will adapt to my foot fully, after several hours of wear. They're made in the USA 🇺🇸. I posted the link on Facebook, with a wonderful review also. Thank you Nuusol team ❤
