Everybody needs customization and the new Volcano Custom Fit insole will make it happen. This 3D insole provides an immediate feeling of comfort and stability. But more than that, this insole has been designed to work in synergy with all the ski & snowboard boots that have a custom fit innerboot. When you heat the boots, you heat the insole, making a new 360° custom fit experience. On the customization scale, Soze calls it 40% custom ready. Fit for everyone !
