Alpinestars Supertech R Vented Boot

Key Features:

• 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.
