My Ortopedic Surgeon has an orthopedics & prosthetics service in his office which I initially used and found totally unreliable. I consulted the internet and found American Heelers in my old neighborhood and gave them a call. I have since had three lifts installed in three different pairs of shoes which cut the weight (using lighter materials & "honeycombing") to reduce the weight of the lift installed shoe by half, thus increasing my mobility. I wouldn't think of using any other company for the service, quality or the price. THANK YOU ILYA!
