2026 Atomic Hawx Ultra 105 S BOA W Ski Boots

The Ultra 105 S BOA W fills a useful spot for skiers who need a genuinely low-volume shell but don’t need an exceptionally stiff boot. The close 98 mm platform provides precision, while BOA® and Atomic’s heat-moldable fit systems give a bootfitter useful tools for refining that shape.

Consider Another Option If

Choose the Hawx Prime if your foot needs more room through the forefoot or instep. A softer boot may also suit skiers who prefer easier flexion, while more powerful skiers may want additional cuff support.

Who is the Hawx Ultra fit designed for?

The Ultra is Atomic’s low-volume Hawx platform, using a 98 mm reference last. Overall fit still depends on instep, heel, ankle and foot shape, so boot fitting remains important.
