BRING RELIEF TO YOUR HEELS: Kaps Corex lifts your heels and therefore relieves the excess pressure, which helps with Achilles tendonitis, heel spurs, heel pain and other heel problems and injuries. The lift is approximately 8.5 mm 0.34 inch. If your shoes are too tight in the heel and ankle, heel lift will reposition your heel upwards making your shoes more comfortable. SHOCK ABSORBTION: Amortization is crucial. Your heels do not like shocks that appear when walking on tough surface. Cork brings pleasant shock absorption to your heels, preventing pain, corns, and calluses. Kaps Corex work well with flats and other shoes with thin or hard soles. Can be used by both men and women. Perfect as well for those with leg length discrepancies and hip injuries.
