Depending on the foot and the boot model, on average about an hour.
Superfeet Kork is a little thicker in volume and will take up more room in the boot. The Kork full-length top sheet is molded from a 3/16" thick sheet of Kork. This makes the product a little denser and offers a little more support. The Kork-Vac full-length top sheet is molded from 3/16" foam. Because we've chosen to use foam full-length it takes up less room in the boot and offers a softer ride.
Custom orthotics made by doctors can cost anywhere from $400 to $500, while Superfeet custom insoles may start around $60 and go up to around $200 depending on the model. The custom Kork is specifically designed for skiing and snowboarding and takes about one hour to make. The Kork product in a ski boot and snowboard boot can last from 5 to 7 years. Taking into consideration the time to make it and the longevity of the product, the Custom Kork is reasonably priced.
Generally it is a good idea to replace the Kork every 5 years because the equipment and the foot may have changed due to weight gain or weight loss, fatigue, stress, or injury.
Custom Kork is a two component product, therefore it offers an increased level of customization and supportive shape to the foot. The Superfit Winter custom insole is a one component product. It does not offer the same level of customization, however, the Superfit Winter product may provide all the support your foot needs.
