I have had chronic Achilles tendinitis since 2003 when the tendon separated from the bone. I got to the point where I just accepted that pain was just now a part of my life. When your ad popped up in my feed, I was a bit skeptical but figured I'd try them and return them if they didn't work. I've been wearing them for two weeks now, and this morning I took my first pain-free step out of bed in 13 years! My only complaint is that my feet hurt BAD after the first day I wore them, but that's likely my fault as I wore them far longer than the 1-2 hours suggested. The first time I ran in them, I knew they were doing something because my legs got sore in ways they didn't previously. But after a total of 35 miles wearing them, I feel better than ever. Thank you! I bought a second pair for my other pair of shoes and bought a pair for my fiancée, who is a waitress and spends most of the day on her feet.
