| VIBRAM® LITEBASE | VIBRAM® LITEBASE is an innovative technology designed to significantly reduce the weight of the sole by reducing the thickness of the rubber, while maintaining the arrangement and structure of the lugs, providing the same performance as a thicker sole. The VIBRAM® LITEBASE technology allows for a reduction of approximately 40 to 50% in sole thickness, from 1.7 mm down to 0.5 / 0.9 mm depending on the type of sole, resulting in a weight reduction of 25 to 30%. This substantial reduction in rubber thickness does not compromise sole traction, durability, or resistance to tearing. |
