This black pair is sized for US 5 \/ EU 38 and features the Alpinestars Multi-Link Control system, which helps limit excessive ankle articulation while providing support against hyper-torsion, hyper-extension, and hyper-flexion. The system also contributes to Achilles and ankle impact protection for demanding street and track applications.\u003c\/p\u003e\u003cp\u003eAn advanced microfiber upper provides lightweight abrasion resistance and flexibility, while soft microfiber flex zones at the front and accordion panels at the Achilles and outside entry area promote natural forward, backward, and lateral movement. A contoured high-modulus shin plate helps protect against impact and abrasion. Dual-density TPU replaceable toe sliders, a replaceable heel slider, and an external side heel slider help provide coverage and dissipate impact energy while supporting controlled sliding during an accident.\u003c\/p\u003e\u003cp\u003eThe SMX Plus boots use an inner instep speed-lacing closure, lateral zipper, and Alpinestars Lace-Lock System for a precise, secure fit.
