The Alpinestars SMX-6 V3 Vented Boots are track- and street-focused motorcycle riding boots designed for riders who want advanced protection, precise control, and comfortable performance. This Black/Silver/Red model is sized US 9.5/EU 44 and features an anatomically shaped fit that supports natural foot movement while improving walking comfort and breathability. The advanced microfiber upper provides lightweight flexibility, durability, and abrasion resistance, while laser-perforated sections, breathable mesh inserts, and vented padding help manage airflow during short and long rides.
Protection is provided by race-derived components throughout the boot. A TPU lateral ankle brace helps support the area between the lower calf, shin, and ankle while promoting controlled ankle articulation. A compact TPU shin plate and layered internal toe box reinforcement help protect against impact and abrasion without interfering with control operation. Front and rear flex zones combine textile materials with soft over-injected TPU to encourage natural forward and backward movement. A TPU shifter zone adds protection on the lower medial side, while the lightweight rubber sole delivers reliable grip on the foot controls.
The SMX-6 V3 uses an Alpinestars Lace-Lock System made from advanced polymer resin for quick, precise, and secure closure. A medial side entry features an elastic-mounted zipper and wide hook-and-loop closure, while the ergonomic elastic gaiter helps maintain a close fit. The streamlined forefoot supports improved contact with motorcycle controls, and the removable dual-compound EVA footbed with Lycra top provides cushioning. An internal shank reinforcement supports the arch and enhances foot protection.
