Sidas Power Strap P3

Maximise the response and comfort of your ski boots with the Sidas Power Strap P3, a stiff elastic booster strap that sharpens flex and control while helping to tame shin bang.

The Sidas Power Strap P3 is designed for skiers who want a more reactive, progressive flex out of their alpine boots without jumping to a new shell. By replacing or upgrading the stock Velcro strap with this strong, elastic design, you tighten the connection between your shin and the boot tongue, which improves fore–aft control and transmits movements to the ski more directly. The P3 level delivers a stiff elasticity suited to powerful piste and freeride skiing, giving you support when you drive the shovels but still letting the boot flex smoothly rather than hinge abruptly. A metal buckle allows precise, strong closure, while reinforced sides resist cuts from sharp ski edges. Ideal for advanced resort and freeride skiers chasing better performance, smoother flex and reduced shin discomfort in variable snow.

• Stiff P3 elasticity: Strong elastic profile tuned for powerful skiers who want a more reactive, supportive boot flex.
• Enhanced ski control: Improves fore–aft support and edge engagement by keeping your shin in closer contact with the boot tongue.
• Reduced shin bang: Elastic stretch helps absorb impacts and smooth out pressure on the tibia when you are charging or skiing cut-up snow.
• Durable construction: High-tenacity strap with side protection to handle repeated flexing and occasional hits from ski edges.
• Precise metal buckle: Robust buckle hardware lets you fine-tune tension for different conditions and skiing styles.
• Includes mounting hardware: Supplied with screws and self-locking inserts; fitting is best done carefully, or by a bootfitter for the cleanest install.
