ONE GOAL: KEEP YOUR FEET WARM |We set out to create our warmest bootie ever, which meant rethinking how booties are made. For the windproofing we went with GORE-TEX INFINIUM™ WINDSTOPPER® fleece-backed fabric, which also lets more moisture escape than any other windproof fabric. Then we added a second fleece layer with Polartec® Power Stretch® Pro™, which is unrivaled in overall loft. The two layers are thick enough that we had to do a wheel well single-layer construction by the ball of the foot to prevent the fabric from rubbing on the crank. We made the bootie high for extra warmth and gave reasonable splash protection. We recommend our Venti Soft Sock for maximum warmth.

DESIGNED FOR THOSE SLIGHTLY COOLER DAYS Keep your feet warm without the hassle of a full shoecover. These toecovers slip easily over the front of your shoes and are held in place by the cleats. The rugged underside of the toe will add grip and resist rips or tears thanks to a silicone print. The toecover can be worn on its own or as a layer between your shoe and shoecover.

DO-IT-ALL DILUVIO We've taken our best-selling Diluvio C and Diluvio Allroad booties and modified, improved and combined them into the all-new Diluvio UL. With improved fit and a better seal thanks to the neoprene enclosure at the top, large reflective rear tabs for visibility, and the flexibility to accommodate any type of cycling shoe, there's little this bootie can't handle.
WHAT IT IS A hard-wearing all-around neoprene bootie that features our premium 3 mm high stretch neoprene, sealed seams, skin-out top edge to seal against the foot, and adjustable opening under the foot to work with any shoe.
