For the outsole, we've selected XS GRIP Vibram® 4 mm rubber, renowned for its high-performance grip and abrasion resistance.
Our designers have worked on a number of construction elements (bi-sole, V-notch under the metatarsals, thin, flexible midsole) to encourage the rubber to crush against the grip. This maximises grip.
Lastly, rubber sections on the heel and top of the shoe provide excellent grip for heel and toe hooks.
