I take this model to my husband who had six fractures ankle a few years ago ... and therefore, osteoarthritis and company! Since he wears Gel-Nimbus, he no longer takes any pain medication. The cushioning is so nickel this is enough to compensate for the fact that he has more cartilage in the joint. While the price is a little high but given that non-stop from 01/01 to 31/12 door, and there he finds comfort unnamed worth. This allows him to work comfortably. I replaced when it starts to limp, signs of pain, and presto, voila! I highly recommend this product!
