BOOSTER STRAP INTERMEDIATE

Booster Strap Intermediate

Engineered to replace stock velcro power straps on alpine ski boots, this dynamic elastomeric boot strap optimizes shin-to-tongue engagement and power transmission. Featuring a two-band semi-stiff elastic webbing construction paired with a heavy-duty micro-adjustable metal cam buckle, it secures the boot liner upper directly against the tibia to eliminate dead space and progressive slack. The elastic recoil properties absorb terrain shock and damp tongue impact to mitigate shin bang while delivering immediate forward pressure and quicker turn initiation.

Designed specifically for intermediate skiers, lighter-weight adults, or aggressive junior racers weighing between 80 to 140 lbs (36 to 63 kg), the intermediate flex rating balances supportive rebound with manageable forward flex. The mechanical metal cam closure allows precise micro-tensioning on the fly, maintaining constant dynamic tension throughout the turn radius without slipping. By eliminating lag between leg movement and boot shell drive, it improves edge control, posture alignment, and overall boot performance.
