Front flex area is constructed with a soft TPU mesh with shaped reliefs for abrasion resistance and natural forward and back movements.
Flexible accordion synthetic leather at Achilles allows natural movement.
Top gaiter follows leg contour and is made of flexible high-grade synthetic leather reinforced with rubber for maintaining shape.
Full length micro-fiber panel on inner side of the boot provides a smooth surface for excellent grip and feel against the bike and protects from abrasion and heat.
Lightweight rubber compound sole offers excellent grip and feel and allows for natural flex as the rider changes position and pressure on the foot-peg.
Flexible, lightweight toe shifter allows feel for changing gears.
Strategically positioned ventilation in heel and shin TPU, and soft TPU mesh on forefoot guides air through the boot.
Extremely protective, flexible and comfortable with excellent aerodynamics. Separate inner boot works with outer boot to form a protective system.
External TPU shin protection wraps around to outer calf and is engineered to spread and dissipate impact energy across the entire surface while remaining compact. Vented sections promote airflow into the boot.
Clip-on toe-slider provides feel and protects the outer toe box structure from abrasion. (Upgradeable to a magnesium slider).
Replaceable TPU heel plate slider protects from impact and reduces friction in the event of a crash.
Outside entry/exit has stretch accordion panel for a close fit and ease of entrance and removal.
Zip mounted on accordion stretch panel gives easy closure with excellent fit. Velcro tabs lock the zip pull closed, keeping it flat and secure.
Micro adjustable ratchet top closure stows tab end inside calf TPU.
Bio-mechanical ankle bracing boot has double hinged inner and outer torsion bars to progressively absorb flex and rotation stress on the ankle and reduce pressure and hyper extension injury to lower leg joints.
Inner ankle brace constructed with fiberglass charged polyamide and ergonomically designed closed cell padding for protection and comfort.
Polyamide compound moldings around foot bed provide impact protection.
Removable anatomic footbed is sculpted for precision fit.
SUPERTECH R is CE certified.
INNER ANKLE BRACE SYSTEM
Separate internal bio-mechanical ankle brace works with the outer structure of the boot to form a protective system allowing full and free movement of the foot, ankle and leg. New research has produced re-profiled double hinged inner and outer trsion bars to give greater impact protection of the ankle and progressively absorb flex and rotation stress, reducing pressure and hyper-extension injury to the lower leg joints.
The inner ankle brace is constructed with a fiberglass re-inforced polyamide compound and ergonomically designed closed cell padding to give protection and comfort.
Alpinestars exclusive lasting process has developed the Supertech R's fit and feel characteristics to an even greater level, ensuring the inner structure allows the rider maximum feedback from the bike.
Specially developed polyamide compound moldings give impact protection while retaining the ease of natural skeletal movement.
Speed lace closure ensures rapid and accurate entry and exit and with micro-adjustability, ensures perfect fitting and security.
