SIDI Hiemx S GTX Cycling Boot - Men's Black/Black Size 45

Hiemx S GTX is engineered for riders that generate power in cold days. The durable upper is layered with Gore-Tex® PFC free membrane ensuring waterproofness and breathability so that moisture doesn’t build up during the ride. Inner Gore-Tex® soft fleece keeps the cold out and is a thermal regulator. The sole is engineered to offer the highest levels of grip and prevent constriction that could reduce blood circulation so that the body temperature is preserved. Dual NUUN™ dial will keep a secure fit for the entire ride. Firmor lateral support ensures greater foot stability during gnarly rides.

Gore-Tex® EPE membrane delivers eco-friendly weather resistance

NUUN™ 001C dials are precision-milled from aluminum for strength and minimal bulk. Their aerodynamic shape reduces drag while SIDI’s integrated handle mechanism allows high-torque tightening when activated. The system also functions seamlessly even when the lever is closed ensuring consistent micro-adjustable fit with every turn.
