Alpinestars Supertech R Boots

Alpinestars' most iconic riding boot, worn by a roster of champions past and present, the Supertech R has undergone a series of evolutions to significantly ramp up to its performance features even further. Innovations include a redesigned compound rubber sole, an update to the ergonomically profiled shin plate and a redesigned front flex area - all of which enhance the podium winning performance of this C.E. certified boot.

• Durable and technical microfiber upper construction offering superb levels of flexibility
• Front flex area is constructed with a redesigned soft TPU (Thermoplastic Polyurethane) over inject on breathable mesh with shaped reliefs for improved abrasion resistance and natural forward and back movements
• Flexible accordion microfibers stretch at achilles to allow natural movement
• Top gaiter follows leg contour and is made from flexible high grade synthetic leather reinforced with PU (Polyurethane) for maintaining shape
• Full length suede microfiber 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
• Flexible, lightweight toe shifter allows feel for changing gears
• Extremely protective, flexible and comfortable with excellent aerodynamics
• 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
• 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, Replaceable clip on shin slider improves protection from abrasion - vented sections promote airflow into the boot
• Integrated replaceable co-injected TPU/aluminum toe slider features easy screw fixing concept that provides feel and protects the outer toe box structure from abrasion
• Replaceable nylon 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 soft TPU stretch panel gives easy closure with excellent fit - additional TPU zipper slider reduces friction in the event of a crash
• Hook & loop closure tab locks the zipper pull closed, keeping it flat and secure
• Micro adjustable redesign ratchet top closure stows tab end
• Developed 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
