The Adjust-A-Lift Heel Lift is a very high quality, versatile item that is helpful in treating a wide range of symptoms arising from the effects of leg length inequality. Low back pain, hip pain and knee pain are some of the more common conditions associated with leg length deficiencies. Adjust-A-Lift Heel Lift has also proved effective in the treatment of some foot and ankle conditions such as plantar faciitis, heel spurs and Achilles tendonitis. The Adjust-A-Lift Heel Lift is made with three layers of extra firm, open cell foam rubber, each 1/8 inch thick, held together with double-sided adhesive. This combination results in only three sizes being needed because the layers can be removed to accommodate the height required up to approximately ½ inch. A top covering of suede leather completes the lift.
