the ds 100 is developed for intermediate to advanced skiers who like a boot with generous foot volume yet being precise and performing. with a flex of 100 and a 100 mm last, a wide range of riders will enjoy skiing in the resort more and longer than before. thanks to the unique construction using two different material stiffnesses for shell and powercage, the ds 100 is the perfect combination of performance and comfort. handling, power transmission and step-in/step-out comfort are way beyond average. with myfit technology, both liner and shell are thermo-formable if needed. the ds 100 is ready for gripwalk soles for smoother walking comfort and better grip.
