The Alpinestars Stella SMX-1 R V2 Vented Boots are women’s motorcycle riding boots engineered for an optimized anatomical fit and dependable protection on the street. Finished in black, this US 10 / EU 42 model combines an advanced microfiber upper with extensive perforation for airflow, comfort, and abrasion resistance. The boot’s ergonomic shaping accommodates a wide range of foot profiles while maintaining a streamlined forefoot design for improved control on the bike.
Feature: The rear flex bellow includes a flex window that also functions as an air intake, promoting ventilation while allowing natural ankle movement. Lightweight microfiber accordion zones at the instep and Achilles area, along with thermowelded flex grooves, provide controlled flexibility for comfortable movement on and off the motorcycle. A soft thermoplastic rubber heel insert works with the rear flex zone to improve comfort around the controls.
Feature: Protective construction includes double-density ankle protectors, an external high-modulus TPU heel counter, lateral ankle reinforcement, an external TPU shift pad, internal toe protection, and an integrated Transversal Protection Frame in the sole to help manage transverse loads. The replaceable bi-injected TPU forefoot slider uses an easy-screw design for convenient service and replacement.
Feature: A reverse zipper and anatomically angled strap closure provide a secure, supportive fit, while the TPR strap puller improves ease of use. The Alpinestars exclusive compound rubber sole delivers grip, water dispersion, and durability. The removable anatomical footbed combines EVA foam and Lycra for support, and the internal mesh lining helps wick moisture and maintain cooling comfort. This women’s-specific boot is manufactured by Alpinestars and identified by vendor part number 2224121-10-42.
