| DYNEEMA® | Ripstop materials containing Dyneema® fibres that are 15 times stronger than steel while being extremely lightweight: up to 40% lighter than aramid, for example. Thanks to its patented technologies, Dyneema® material has exclusive directional characteristics that provide an unmatched strength-to-weight ratio. This ripstop Dyneema® fabric guarantees extreme tear resistance. |
| VIBRAM® LITEBASE | Vibram® Litebase is an innovative technology designed to significantly reduce the weight of the sole by reducing the rubber thickness while maintaining the lug layout and structure, delivering the same performance as a thicker sole. The Vibram® Litebase technology achieves a reduction of approximately 40 to 50% in sole thickness, from 1.7 mm to 0.5 / 0.9 mm depending on the sole type, resulting in a 25 to 30% weight reduction. This substantial reduction in rubber thickness does not compromise sole traction, durability, or tear resistance. |
| VIBRAM® MEGAGRIP ELITE® | Vibram® Megagrip Elite® is an advanced technology designed to provide unbeatable grip on both dry and wet surfaces, making it the ideal choice for trail running on steep and challenging terrain. Built for elite athletes, this cutting-edge technology is engineered to withstand the toughest conditions, from vertical kilometre races to 100-mile endurance challenges. After hundreds of hours of testing and multiple iterations, Vibram® Megagrip Elite® technology is finely tuned to ensure maximum traction, stability, and performance on race day. |
