Keep your feet warm and dry when the cold bites

Don't let freezing temperatures, slush, or mud put the brakes on your gravel adventures. The Sidi Hiemx S GTX is a robust winter cycling shoe designed to tackle the harshest winter conditions. Equipped with a PFC-free Gore-Tex ePE membrane, these boots seal out wind and water while allowing moisture to escape when you are working hard. On the inside, a soft fleece lining acts as a cozy thermal regulator, ensuring your toes stay warm even on long, freezing winter rides.

To maximize your power transfer, Sidi has equipped the shoe with an MTB X2NC sole made from carbon and nylon fibers. With a stiffness index of 7, it delivers great pedaling efficiency while offering excellent grip and stability when you need to dismount on slippery or muddy sections. The micro-adjustable Tecno-3 dial system, reinforced with durable Dyneema laces, lets you customize the fit across the entire foot—even while wearing winter gloves.
