Features
The Sidas Power Straps are designed to enhance the flex of your ski boots, improving ski control and overall performance. By using an elastic strap, these Power Straps not only boost flex but also provide added comfort to the tibia when combined with the ski boot’s tongue. Available in four different flex levels (P1 for the softest flex to P4 for the stiffest), they allow you to customize your ski experience to suit your preferences.
Each strap features a durable metal buckle for precise and powerful tightening, as well as a side protection reinforcement to guard against damage from ski edges during use. Made with high-tenacity polyester and featuring a redesigned buckle, these straps are built to perform in the most demanding conditions.
- Enhanced Ski Boot Flex: Improves the flex of your ski boots for better ski control and precision on the slopes.
- Customizable Performance: Four elasticity levels (P1 to P4) to match your skiing style and control needs.
- Improved Comfort: Elastic design reduces pressure on the tibia and enhances comfort with the boot’s tongue.
- Durable Design: High-tenacity polyester construction and side reinforcements for added protection and longevity.
- Precise Fit: Metal buckle ensures secure and powerful tightening for optimal performance.
- The Straps are supplied with 1 pair of screws + self-locking insert.

AI FAQs
AI generated FAQs about the Powerstrap Race
How do I know what size to order?
Powerstrap Race is sold by flex level rather than by size, with P2, P3, and P4 options available. Choose the flex level that matches how much added boot-flex support and control you want, and talk with a bootfitter if you're unsure which level suits your boot and skiing style, since mounting these straps is a technical operation.
Can I adjust how snug these boots fit around my ankle and calf?
The elastic Power Strap tunes boot flex and tibia comfort against the boot tongue rather than ankle or calf snugness, using a durable metal buckle for precise, powerful tightening. You can adjust strap tension to dial in flex support and reduce pressure on your tibia, but this strap does not adjust the fit around your ankle or calf.
Will the buckles and straps stay secure over a full season?
The metal buckle delivers secure, powerful tightening, and the strap uses high-tenacity polyester built for demanding conditions. Side-protection reinforcement helps guard the strap against damage from ski edges during use.
How much feedback and control will these ski boot power straps give me?
The elastic Power Strap enhances ski-boot flex for better ski control and precision. Its metal buckle provides precise, powerful tightening to help you dial in the strap’s response.
Are these ski boot power straps flexible enough for learning, or too stiff?
Powerstrap Race is available in P2 through P4 flex levels, with P2 offering the softest flex in this lineup and P4 the stiffest. This version does not include the softer P1 option, so it suits skiers looking for moderate to stiff flex tuning rather than the softest beginner-level flex.
