A ski mountaineer's dream. SCOTT's POWERLITE 4-buckle and 2-buckle ski mountaineering boots make no compromise in skiing performance when it comes to incredibly lightweight and comfort features. With an ergonomic fit and ease of use, these boots don't just ski well for how light they are, they ski incredibly well, period.

POWERLITE Boots are built from Grilamid^®, making them stiffer, lighter, and thinner than other lightweight shells. The POWERLITE Frame uses reinforcing ribs throughout the shell and cuff to give maximum rigidity while maintaining their light weight. The new POWERLITE shells of the S1 boots have the optimal synergy of superior performance and very light weight. An evolution of the POWERLITE COSMOS and SUPERGUIDE, the S1 brings the combination of light weight, stability, and performance to the next level. 

• Precise, solid, secure skiing
• Performance with their super-light, stiff, supportive Grilamid^® shell
• Instant comfort
• Highly refined
• Pre-punched shell
• Huge range of motion for walking
• Full-length rubber sole for rugged and varying terrain
• Expanded PU inserts in the sole for insulation
• Comfort, and increased ski feel

Easy to operate, the new POWERLITE rear hook mechanism combines strength and stability in ski mode with total freedom when skinning or walking. This next generation hook mechanism locks automatically when downhill skiing. 

Full-length Vibram bi-density rubber under the instep area provides maximum grip when scrambling over any terrain that isn't snow. The bi-density composition has firmer black rubber around the sole's perimeter to provide durability and superior edging power in step-in bindings. Softer red rubber in the sole's midsection gives maximum grip for scrambling.

Shock Damper Inserts are expanded PU foam inserts in the shell's inner sole that act as a shock absorber when skiing, and add insulation, comfort, and increased ski feel.
