Nordica Sportmachine 3 100 BOA Ski Boots

The Nordica Sportmachine 3 100 BOA is a medium-flex, wide-fit alpine ski boot built for skiers who want Sportmachine comfort with the precise, micro-adjustable hold of the BOA® Fit System.

What Sets It Apart

• BOA® Shell Wrap: The single-dial BOA® Fit System creates a uniform wrap around the lower shell, helping reduce pressure points while improving heel hold and edge-to-edge control.
• 102mm Sportmachine Fit: Nordica’s highest-volume Machine platform gives skiers a roomier fit through the forefoot without stepping away from all-mountain support.
• 100 Flex: A balanced flex profile offers supportive response for confident intermediate and advancing skiers without feeling overly demanding.
• Redesigned Shell and Liner: The Sportmachine 3 BOA platform is built to improve fit, comfort, and skiing performance while keeping the wider chassis feel.

Ideal For

The Sportmachine 3 100 BOA is ideal for adult skiers who want a wider, comfort-focused alpine boot with easier fit adjustment than a traditional buckle-only shell. It is a strong match for resort skiers who value all-day comfort, secure heel hold, and a supportive but approachable flex.

How It Compares

Compared with Nordica’s narrower Promachine and Speedmachine families, the Sportmachine line uses a 102mm wide-fit chassis for more volume and comfort. Within the Sportmachine BOA collection, the 100 flex sits below the 110, 120, and 130 models, making it more forgiving while still offering reliable support for everyday all-mountain skiing.

Bottom Line: The Nordica Sportmachine 3 100 BOA is a wide-fit alpine ski boot with BOA® precision, approachable support, and comfort-driven performance for resort skiers.
