We love the Dalbello Krypton ID ski boots because we love going down cliffs overcome narrow slopes fight your way through the trees and down the steepest slopes of the mountain and these boots too. Featuring an incredibly stiff 130 Flex stiffness Krypton gives us power necessary to control our big mountain poles on pistes intended for experts only and the narrow 98mm last is ideal for skiers with thin legs or experienced shredders people like us who value a tight and precise fit.
