K2 Powerfit Pro Wrap BOA Liner

The PowerFit Pro Wrap BOA® Liner is K2’s top-tier aftermarket ski boot liner, designed to increase precision, heel hold, and support—especially for riders who want a more locked-in, responsive fit than stock liners provide.

Best for: Advanced to expert riders, freeride, big-mountain, and riders upgrading worn or packed-out liners.

Fit & Compatibility

Category: Ski boot liner (aftermarket / replacement)

Compatibility: Designed to work in most traditional ski boot shells, not brand-locked to K2 boots

💡 Pro tip: This liner is ideal if your shell still has life left, but the liner feels packed out or sloppy—especially in the heel.

Key Features

• 3-Point Wrap Construction
• Wrap-style design delivers even pressure around the lower leg and instep, improving heel hold and edge control while reducing pressure points.
• BOA® Fit System (Liner-Specific)
• Independent BOA dial tightens the liner shell uniformly, allowing micro-adjustments without over-cranking boot laces. Especially useful for fine-tuning fit on the hill.
• Intuition® Foam
• Heat-moldable Intuition foam provides:
• Lightweight construction
• Excellent warmth
• Long-term shape retention compared to standard EVA liners
• High-Density Cuff & Reinforcement Zones
• Adds stiffness and support for aggressive riding and higher-speed control. Helps revive softer boots or add backbone to all-mountain shells.
