The Alpinestars Stella SMX-1R V2 boots are women’s motorcycle riding boots designed with an anatomically engineered fit for comfort, control, and protective performance. This black pair is sized US 10 / EU 42 and is identified by manufacturer and vendor part number 2224621-10-42. The main upper uses advanced microfiber for lightweight comfort, durability, and abrasion resistance, while the ergonomic boot shape streamlines the forefoot to accommodate a broad range of foot profiles.
Protection and support are built into the design for street and sport riding. The innovative heel counter support system works with the anatomically angled strap closure to improve fit, structural integrity, and rider support. Double-density ankle protection, an external high-modulus TPU heel counter, lateral ankle protection, an internal toe box, and an integrated replaceable bi-injected TPU forefoot slider help protect key impact and abrasion zones. The sole incorporates Alpinestars’ Transversal Protection Frame (TPF) to help guard against transversal loads while maintaining useful flex and control.
Comfort and mobility are supported by microfiber accordion flex zones at the instep and Achilles area, thermowelded flex grooves, and a rear flex bellow with an integrated ventilation window. The reverse zipper and front hook-and-loop closure provide convenient entry and a secure fit across the instep, while the TPR puller and aramidic fiber wires support easy operation and closure durability. An exclusive Alpinestars compound rubber sole provides grip, water dispersion, and durability for confident movement on and off the motorcycle. Inside, the removable anatomical footbed combines EVA foam and Lycra for cushioning and support, while the internal mesh lining promotes cooling comfort and moisture management.
