This clever lace system extends all the way to the toe to help accommodate for a wide variety of different foot shapes. This shoe also incorporates a stiff midsole with concaved forefoot, which further enhances support and places the toes into a more powerful position.
The sole unit features a large section of our recycled Eco rubber, while sticky Zenith Quattro is used in the climbing zones at forefoot and heel.
