EVA 3 / 4 orthopedic insole is developed by Australian foot therapists. It is a 3 / 4 length orthopedic insole, which can effectively treat heel pain, knee pain, low back pain or fatigue. Double layer orthopedic technique was used. The combination of a strong support E.V.A. and a soft 2 mm duracontex top layer makes this orthosis very effective, providing comfort and support as well as cushioning.
