swede, when I went to their office and they made the insoles I was told to expect them to last a year under normal use. I'm still taking things very easy by my standards and I can see the edges curling on the top liner. I guess there are several ways insoles can be made with different materials. These are a base layer of dense cork with a top layer of a liner type material. It was heated, formed, and ground to the current fit. I guess I should look at other custom options that will last longer, especially under wet conditions as I was told that will shorten the life of the cork based insoles.
