Customer Reviews
Advised by my physio to buy "a pair" of these, I bought two, and after les than a week bought another four pairs!
I actually cheat! I only need them for one foot, (ankle) so I simply wear one on the affected foot with my normal socks over the top, ok in winter, but summer may be another story! Still, at least I can wear a fresh sock each day to give the laundry basket time to fill up!
Great fit and great support!
