ALPINESTARS(MX) Tech 3 Boots — EU 48, Over-Calf, Black/Gray

The Tech 3 boots combine advanced polymer protection with a lightweight, flexible microfiber construction for off-road performance. 🏁

Upper construction uses innovative, abrasion‑resistant microfiber with flexible front and rear bellows to improve comfort in high‑flex areas. The toe box is reinforced with high‑abrasion synthetic material while an extended polyurethane gaiter helps seal out excessive water and dirt.

Protection features include a contoured TPU calf protector plate, higher medial TPU protector, outer lateral ankle TPU, heel counter and a rear TPR gaiter patch for impact resistance and comfort on rear flex. An injected TPU shin plate connects to the medial protector panel for integrated support.

The closure system features three polymer buckles with a ratchet-and-memory quick‑release system and self‑aligning design; all buckles are replaceable. The ergonomic TPU triple buckle straps wrap the front flex area without compromising movement, and a bio‑mechanical medial blade system supports controlled front‑rear flex.

Footwear tech includes a one‑piece injected dual‑compound TPU foot shell reinforced by a metal shank and a co‑injected toe reinforcement, soft ankle foams for shock absorption, a replaceable EVA footbed with textile lining and a high‑grip replaceable rubber outsole.

Composition: 68% TPU, 21% microfiber, 4% polyurethane, 4% thermoplastic rubber, 3% PU nubuck synthetic suede. Inner lining: 94.45% textile, 5.55% synthetic PU.
