Here is the right replacement insole for your Comfort Fit shoe. It consists of
a layer of cork. This is the layer between the tree trunk and the bark of the
cork oak. and thermoformable MFS foam. A supporting polyurethane element is used
under the arch of the foot; a cushioning shock absorber made of Poron is incorporated
under the heel. All of this is hidden under a flat layer of nylon mesh, which
draws moisture away from the foot and has a positive effect on the foot climate.
