When still relatively new, Rapha’s Deep Winter overshoes take a bit of cajoling to get on, but after a bit of use, they slip on easily. The zip at the rear is sturdy and doesn’t snag, dig or rub against your leg, and it locks into place with a Velcro tab.
The exterior is a three-layer water and wind resistant fabric that stands up well to both elements. We’ve worn these during a few hour-long rides in torrential rain, and they kept our feet dry, no doubt helped by the effective taped seam that runs along the top. The fleece lining isn’t the most luxurious out there, but when combined with some warm winter socks, our feet were kept warm down to low single figure temperatures.
The sole is reinforced with Kevlar to keep it from falling apart and, when you examine it with your fingers, it’s noticeably tough, which should bode well for the longevity of these overshoes.
The fit is very good – the Deep Winters have a sleek profile and are free from any gaps that could allow wind and water in because they sit snugly against your shoes and legs. Although they provide a close fit, they aren't too tight either, so don't push Boa adjusters uncomfortably into your feet.
