One of the most technically advanced boots on the market. Ideal for people who would like a lightweight technical & a comfortable mountain boot. The Total Traction sole unit provides outstanding grip on any type of mountain terrain, very stable thanks to the low profile & lateral stiffness, & is extremely dexterous for climbing. Comfort is enhanced by PU inserts in the heel & metatarsal area which add 30% extra cushioning (compared to traditional mountain boot soles) for long hard approach/trekking in cold icy conditions. A little bit of flex ensures greater comfort without reducing the ability to take a fully rigid crampon, while Scarpa's new Ergo Fit system provides amazing heel & foot holding, & control on any angle terrain while climbing or walking.
