Now don't get me wrong, I do believe orthotics (Heel cup, posts, wedges, MLA pads, custom molded shells, etc.) work to reduce pain, improve balance and alter the kinetics and kinematics of gait!
Graceyfeet is a tool for the toolbox to control pain and improve function. It can be complimentary to existing orthotic devices or for athletes who have soured on the use of orthotics altogether. It can go next to the skin and be cut for cast shoes, wrist pads, crown pads for helmets, slide pads, glove/mitt pads, chest pads, shoulder pads, and anywhere reduced pressures are desired. It's anti-microbial and anti-bacterial! It can be washed and dried in a machine! I can silkscreen a logo or player's name on it! It's very cool stuff.
So, you've read this far. Congratulations! You've earned the right to know more...
