Almost every component of the Supertech R Vented 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 extensive perforations throughout for maximum airflow, innovations derived using feedback from Alpinestars involvement in top flight racing 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.
TPU shin plate: redesigned to absorb impacts better and boost abrasion resistance in a critical zone.
Replaceable shin slider: adds an extra abrasion barrier and is easy to swap after wear.
TPU stretch panel with zip: simplifies entry and exit while delivering a closer, optimized fit.
Hook‑and‑loop zipper keeper: secures the zipper pull so it stays in position while riding.
Micro‑adjustable top ratchet: fine‑tunes the calf closure for a personalized, secure fit.
Ventilated microfiber upper: laser‑perforated zones increase airflow while maintaining abrasion resistance and flexibility.
Redesigned front flex area: enhances impact and abrasion performance while supporting natural fore‑aft movement.
Front flex ventilation channels: increase airflow for added breathability in warm conditions.
Redesigned rear stretch bellow: improves natural forward and backward movement for freer control.
TPU over‑injected top gaiter: improves grip and sealing around the leg for a cleaner, more secure closure.
Synthetic microfiber medial panel increases abrasion resistance in the bike-contact area.
TPU shifter zone provides added protection on the lower medial side.
Inner bootie with external toe area soft TPU reinforcement delivers impact protection, with additional ankle padding for increased coverage.
CE certified to EN 13634:2017.
Replaceable co-injected TPU/aluminum toe slider protects the toe area against abrasion.
Replaceable heel plate slider enhances sliding performance and protects the heel in the event of a crash.
Sole constructed from a lightweight rubber compound for reduced weight and wear durability.
Separate, internally updated biomechanical inner bootie constructed from 3D mesh material with structural reinforcements.
