The Alpinestars SMX-S motorcycle boots are designed for riders who need dependable protection, flexibility, and all-weather comfort. This black riding boot features a durable microfiber upper paired with a waterproof, breathable membrane to help keep feet comfortable in changing weather conditions. The US 6.5 / EU 40 fit is suitable for riders seeking a secure, performance-focused motorcycle boot for street and sport riding.
Protection is provided by an ergonomically optimized TPU shin plate, lateral TPR-injected ankle support, and double-density TPU ankle protectors positioned beneath the upper on both the medial and lateral sides. Internal toe box protection reinforces the front of the boot while maintaining rider feel and control. An integrated, replaceable bi-injected TPU slider uses an easy no-screw fastening concept for faster replacement and convenient maintenance.
The medial entry system combines an elastic-mounted zipper with a wide hook-and-loop closure for a flexible, secure fit. Its large aperture supports easier entry and removal. A technical TPU shift pad helps protect the boot while improving grip and shifting control. Inside, the removable dual-compound anatomical footbed combines EVA and Lycra for cushioning, support, and comfort. The compound rubber sole provides reliable grip, water dispersion, durability, and improved feedback through the foot controls.
