I had an accident early in 2014 at age 68.....fell down a couple stairs onto concrete. After a couple surgeries on upper leg and hip and several metal items added to my leg and hip, I rehabbed diligently to walk again. After 6 months, PT realized the damaged leg was now shorter which was causing balance, stride and back pain. A local shoe repair shop (no longer in business) referred me to American Heelers. I have great success walking, exercising and hiking with the lift without pain. They put the lift between the shoe and sole so the shoes grip and feel the same on all surfaces but have the lift to keep me balanced. My orthopedic doctor is very happy with the shoe lift and what it does for my overall Skeletal issues. Thank you so much for my quality of life improvement with this lift process.
