Description
The SIDI Hiemx S GTX Cycling Boot in Black/Yellow Fluo, size 46, is designed for cyclists riding in cold conditions. Its durable upper features a Gore-Tex PFC-free membrane that provides waterproof protection while allowing breathability to prevent moisture buildup. Inside, a Gore-Tex soft fleece lining offers thermal regulation and keeps cold air out.
The composite X2CC sole has a stiffness rating of 7 and delivers excellent grip, while its design avoids constriction to maintain blood circulation and preserve body temperature. The boot includes a reinforced toe for protection against rocky terrain and an anatomic heel for comfort during extended rides.
Lateral stability is enhanced with the Firmor system, and ripstop coverage adds water resistance, scratch protection, and flexibility. Closure is secured by dual NUUN 001C dials, made from precision-milled aluminum for strength and a low profile. Their aerodynamic shape reduces drag, and the integrated handle mechanism ensures firm, micro-adjustable tightening throughout the ride.
This unisex cycling boot uses a 2-bolt cleat pattern and combines dial and Velcro closures for a secure fit. It is waterproof and suitable for winter cycling with optimized thermal regulation.
