Megagrip is the flagship sole of the Vibram brand, used in approach and trail running shoes. It is based on an aggressive tread with rows of evenly spaced lugs, made of a special mixture of abrasion-resistant rubber. It guarantees great adhesion of the shoes to the ground – regardless of whether it is rock (also wet), gravel, forest floor, or even, to some extent, wetland.
