Are you ready to combat the elements in style so you can train outdoors through cold and wet weather? Castelli has you covered with this Rain or Shine (RoS) series, and the RoS Shoe Cover shows off all the characteristics you desire in such gear. The concept within the Castelli collection is a designation for products that are designed to excel in dry weather yet provide significant water protection when you get caught in the rain. All too many products struggle to effectively find this balance, especially in a serious performance piece that pros or enthusiasts can exploit to their advantage.

This RoS shoecover is made with a stretch water resistant and windproof breathable fabric, with a fleece liner, and is cut high to the base of the calf muscle for warmth in dry weather. For rainy conditions, the designers moved critical seams toward the outside, where they're less exposed. The zipper is also moved to the side, and Castelli has included a molded reflective heel cup for visibility. Digging deeper into the details, you can appreciate how the contoured seams around the ankle provide an ideal, comfortable fit even as you have slight articulation throughout the pedal stroke. An Internal gripper around the cuff edge helps to truly seal out water from the top, without a circulation restricting elastic. The top of the zipper has a nice rubber pull and a small zipper garage to protect your tights. A reflective heel cap and a textured grip pull at the back of the heel makes it much easy to take the RoS Shoe Cover on and off.
