Calling runners: winter training made possible with NANOspikes™. It uses advanced polymers and spike designs that feel extremely light and sleek and are at the same time incredibly tough and durable.Lightweight and Ergonomic HarnessThe elastomer harness is thinner and lighter than ever without sacrificing strength or durability. It has an uniform stretch over the entire foot.Reinforced Eyelets and ConnectionsBy sharing a central connection to the harness between the front and rear traction plates, movement of the plates is minimized while achieving superior fit on the shoes. The overmolded eyelet technology fuses a stretchy and flexible elastomer material to a high abrasion-resistant polymeric insert, increasing durability and creating a more streamlined fit.Evolved Spike DesignA new kind of spike was made by moving tungsten carbide studs away from the foot and creating a stepped and tapered shock absorbing cleat around them. The tungsten carbide studs have superior wear resistance and produce an unrivaled bite into ice, while the steps on the cleat engage all other types of terrain. Durability and reliability are optimized by holding the studs in place with a lightweight aluminum anchor. A base height 0.125" and a spike height 0.213" for the low profile traction plates.Dual Compound and Upward TractionBy fusing a more flexible material to supportive plates, comfort and performance can coexist. The plates create a platform against the shoe, more evenly distributing forces and eliminating pressure points. The energy of each step is transferred to the tips of the carbide studs. Small cleats are interfaced with a shoe for upward traction to prevent movement between the plates and the shoe.Hinged Front Plate and Built-In Snow ReleaseA flexible joint is integrated into the front plate enhancing fit and durability. An integrated snow release system was designed into traction plates.
