The lightweight Atomic Redster Worldcup Skate is our top skating boot for competitive skaters, packed full of World Cup technology. The genius of this boot is the new Custom Fit we’ve added to it: simply heat the liner with a heater and it molds to your foot for a completely personalized liner in minutes. It also comes with an innovative Carbon 3D Chassis with exceptional torsional rigidity. So all your physical strength is directed into your ski for explosive acceleration. At the same time, the ultra-stiff outsole ensures maximum stability for skating. And another clever innovation is the Precision Closure system, which combines ratchet closure, wrapping lace and dissociated quicklace for a really precise fit and excellent traction.
