I ordered my M7 Sport Ankle Tape from Amazon.com and I started to use it when I had an ankle sprain (very painful experience). The good thing was that I had my ankle brace and I use it right away.
I started to feel some discomfort at the begging which I suppose was normal cause my ankle was in deep pain, but in a few hours, I felt much better.
M7 Sport Ankle Tape decreased pain and disability after few hours of wearing. During the injury, I was wearing this ankle tape for 5 days, had showers and the most important thing I was able to walk (almost no pain). The tape was a big help for me!
