Alpinestars' ankle brace protection system provides biomechanical support between the calf, shin, and ankle, helping limit hyper-torsion, hyper-extension, and hyper-flexion while protecting the Achilles area and ankle. Dual-density TPU ankle protectors and a race-derived TPU shin plate add targeted impact coverage.\u003c\/p\u003e\u003cp\u003eThe Alpinestars Lace-Lock System uses an advanced polymer resin closure for quick, precise, and secure adjustment.
