Alpinestars Supertech R V2 Fluro Yellow/Black Boots

Almost every component of the Supertech R Boot, Alpinestars definitive racing boot as worn by a roster of champions past and present, has undergone a rigorous program of upgrades to sharpen its performance features even further. Featuring innovations derived using feedback from Alpinestars involvement in top flight racing, key elements include a newly redesigned front flex area, a redesigned rear bellow, a redesigned top gaitor, a new shifter and shin plate, a new shin slider and a new inner bootie, all of which enhance the comfort, protection and the performance of this boot to a new class-leading high.

Key Features
• Closure system: TPU stretch panel with side zip speeds entry/exit and creates a close, race-fit wrap around the lower leg.
