What you need in an overshoe is something that's tough, water-resistant and easy to put on. These tick all the boxes.
They’re tough thanks to Kevlar on the toes and heel, the PU coating shrugs off the elements and they’re easy to get on because of the open sole – which has a Velcro strip.
The H20s are available in five sizes and come with an antibacterial lining… made of bamboo. This is the mountain bike/commuter model; a Tarmac H20 is available for road riders.
