The Atomic Hawx Ultra 130 RS Ski Boot is an extremely powerful alpine boot with a Redster-like feel. With a flex value of 130 and a last value of 98mm, the Hawx Ultra 130 RS enlists the expertise of Atomic’s slimmest profile to dial-in precision and amplify power. Stiff in its construction and narrow in its fit, the Hawx Ultra 130 RS has a distinct race-like feel in an all-mountain frame. The result is a boot that’s a bit more versatile than a Redster, with an all-mountain profile designed to charge in a variety of snow conditions at a wide range of speeds. Equipped with an Energy Backbone in its Prolite Shell construction and a 50mm Quick-Release Strap above the buckles, the Atomic Hawx Ultra 130 RS Ski Boot endows expert skiers with an exceptionally strong, stable, and supportive ride tailor-made for powerful performance in a featherlight frame.
