Crafted with an anatomically engineered fit, these boots feature a main upper constructed from advanced microfiber, providing excellent abrasion resistance and durability for demanding riding conditions. The innovative heel counter support system works in conjunction with a strap closure to enhance fit, support, and structural integrity, ensuring confidence on the bike. The rear of the heel counter includes a soft Thermoplastic Rubber (TPR) insert that integrates seamlessly with the rear flex zone, allowing for improved ankle mobility and comfort during extended rides or aggressive maneuvers. The rear flex bellow is equipped with a flex window that acts as an air intake, promoting airflow and helping to keep your feet cool and dry during intense riding sessions. \u003c\/p\u003e\u003cp\u003eAdditional features include a new ergonomic Thermoplastic Polyurethane (TPU) shift pad for increased durability in a high-wear area and an ergonomic boot shape that offers a wide-ranging fit for various foot profiles. The evolved closure strap is anatomically angled to follow the natural shape of the rider’s instep, providing a secure fit while allowing for flexibility. The front Velcro® closure system ensures quick and reliable fastening, with a TPR puller for ease of use. Aramidic fiber wires reinforce the strap system to maintain strength while remaining lightweight. The exclusive Alpinestars rubber sole features a grip pattern designed to improve feel, grip, water dispersion, and durability. The sole also incorporates the Transversal Protection Frame (TPF) for added protection against transversal loads, enhancing safety. \u003c\/p\u003e\u003cp\u003eThe boots’ instep and Achilles’ accordion flex zones are made from lightweight microfiber, optimizing comfort and maneuverability both on and off the bike.

The reverse zip closure provides convenient entry and removal, while the double density ankle protector layered under the upper offers abrasion resistance and impact protection. An integrated, replaceable bi-injected TPU forefoot slider features an easy-screw fixing for quick replacement, extending the longevity of the boots. External high modulus TPU components, including the heel counter, lateral ankle, and shift pad, further improve shock absorption and durability. The internal toe box protection underneath the upper enhances durability and rider feel. The removable anatomic foot-bed, made of EVA foam and Lycra®, delivers additional comfort and support, complemented by an internal moisture-wicking mesh lining for cooling comfort during long rides.
