The SIDI Hiemx Cycling Boot delivers the warmth, comfort, and weather protection we need to continue riding through the cold, wet winters. The anatomically designed, high-tech upper and GORE-TEX membrane offers exceptional waterproof protection without sacrificing breathability, and the strategic ripstop top layer keeps excess water from seeping in. SIDI includes the Dyneema Dialing system to find a secure fit, which is easy to adjust with or without gloves, and the moderately stiff X2NC sole optimizes our pedal stroke and provides unmatched grip on any surface.
