The Alpinestars Stella SMX-6 V3 Vented Boots are women’s motorcycle boots designed for track and street riding. This Black/White model in women’s US 9 / EU 41 uses a dedicated female fit to provide secure support, riding comfort, and precise control on the motorcycle. Alpinestars manufactures these performance riding boots with an advanced microfiber upper, laser-perforated ventilation zones, and race-derived protective components for riders seeking a balance of flexibility, breathability, and abrasion resistance. Manufacturer part number 2223425-21-41 is also listed as vendor part number 2223425-21-41.
Feature: Advanced microfiber upper provides lightweight abrasion resistance, durability, flexibility, and breathability. Feature: Laser-perforated upper sections, breathable mesh inserts, and air vents at the heel counter and shin plate help promote airflow during short or extended rides. Feature: TPU ankle brace system supports the area between the lateral calf, shin, and ankle while helping protect the ankle and Achilles. Feature: Race-derived TPU shin protection and layered internal toe protection help guard against impact and abrasion while maintaining a streamlined fit under riding pants. Feature: Front and rear flex zones combine textile and soft over-injected TPU areas to support natural foot movement while improving impact and abrasion protection.
The Alpinestars Lace-Lock System uses a durable polymer resin closure for quick, precise, and secure fastening. A medial-side entry system combines an elastic-mounted zipper with a wide hook-and-loop closure, while the ergonomic elastic gaiter helps maintain a close fit in changing riding conditions. The streamlined forefoot supports smooth interaction with motorcycle controls, and a dedicated TPU shifter zone helps protect the lower medial side of the boot. These features make the Stella SMX-6 V3 suitable for sport riding, commuting, and track use where dependable foot and ankle coverage is important.
Inside, the boot includes a removable dual-compound EVA footbed with a Lycra top layer, an internal shank reinforcement for arch support, and perforated padding throughout the collar, bellows, and ankle for added comfort and ventilation. A lightweight rubber sole provides grip on the foot controls, while the boot’s ergonomic construction supports walking comfort between rides.
