Castelli has taken their best-selling Diluvio C and Diluvio Allroad booties and modified, improved and combined them into the all-new Diluvio UL, a shoe cover that fits over any shoe type, making it a great choice for road, mountain, gravel or adventure use. With improved fit and a better seal thanks to the neoprene enclosure at the top, large reflective rear tabs for visibility, and the flexibility needed to accommodate any type of cycling shoe, there's little this bootie can't handle.

The hard-wearing all-around neoprene bootie features Castelli's premium 3mm high stretch neoprene, sealed seams, skin-out top edge finish to seal against the foot, and adjustable Velcro adjustable opening under that combines with the larger opening and stretch of the neoprene to fit all sole and pedal designs
