Why a ski strap (booster/power strap) changes the experience
When you put on ski boots, the fit and support of the shin/leg in the shell are crucial: good contact between the shin and the boot tongue improves ski control, precision, comfort and responsiveness when turning, carving or in challenging situations. But the original ‘stock’ straps are not always sufficient, especially if the boot leaves a gap or if the shin is not sufficiently comfortable. An elastic strap/booster strap improves the flex of the boot, adjusts the fit, strengthens contact and reduces shin impact.
What Sidas straps offer
-
Adjustable flexibility & improved responsiveness — Sidas straps are available in several levels of elasticity (P1 = flexible → P4 = rigid), allowing you to choose a boot behaviour suited to your style, weight, level or skiing conditions.
-
Better shin/tongue contact & increased comfort— The strap eliminates the space between the shin and the tongue of the boot, which improves energy transfer, precision of support, feeling of control, and can reduce ‘tib-bang’ (shin pain, pain related to support).
- Ski control & turn precision — With a precise fit and better flex transmission, skiers gain control, responsiveness and the ability to engage their edges — a significant benefit on the piste, hard snow or for technical skiing.
-
Customisation & adaptation according to use — Whether you are looking for comfort (soft strap) or performance/rigidity (rigid strap), the range allows you to adapt the strap to your body type, level and type of skiing (leisure, piste, freeride, performance).
- Durability & robustness — Made from high-tenacity polyester, with a metal buckle for a secure fit and side reinforcements to protect the strap from ski edges — ensuring longevity even with intensive use.
Who is this collection of ski straps for?
- Regular skiers who want better support, comfort and control, whether on the piste, freeriding or skiing in challenging conditions.
- Those whose ‘original’ boots lack support or have an imperfect fit — the strap allows you to ‘customise’ the boot.
- Skiers who are sensitive to shin comfort, support and leg feel — shock reduction, better contact and better transmission.
- Demanding skiers looking for performance, precision and responsiveness — especially on hard snow, technical turns, carving and fast descents.
- For those who want modular equipment — possibility of adjusting the elasticity according to level, body type, and skiing style.
Expert advice & best practices
- Choose the right level of flex (P1 → P4) according to your body type, weight, style, and use: flexible for comfort, rigid for performance.
-
Install the strap correctly — Sidas straps come with screws and inserts; installation may require the assistance of a boot fitter for optimal and secure installation.
- Adjust the tightness properly — ensure that the shin is in contact with the tongue without causing discomfort: the right tightness improves precision without sacrificing comfort.
- Test gradually after installation — take a few runs to check comfort, support and transmission before setting off for a long day or challenging skiing.
- Maintenance and inspection — check the condition of the strap, buckle and fastenings regularly, especially in case of intensive use, to ensure safety and durability.
