| Vibram® Ascension Expedition Litebase | Vibram Litebase is an innovative technology designed to considerably reduce the weight of the sole by reducing the thickness of the rubber, while maintaining the layout and structure of the lugs, giving it the same performance as a thicker sole. The Vibram Litebase technology reduces the sole's Thickness by around 40-50%, resulting in a 25-30% reduction in weight. The substantial reduction in rubber thickness does not compromise sole traction, durability or the risk of laceration. |
| Boa® Fit System | This system allows for easy, quick and ultra-precise customised boot adjustment. Easy one-handed operation for fast opening and closing. |
| Insulated Carbon Innersole® |
Carbon insole with patented Double Insulation, which on the one hand ensures minimum weight and maximum rigidity, and on the other offers outstanding insulation. |
