Do you really have to wear bike winter shoes in winter when you get in the saddle? For the short way to the bakery, that might be a bit excessive. But when you're plowing through the snow on your mountain bike off-road, warm, dry feet are a really tempting prospect, aren't they? Even your road bike rides will be even better with winter shoes. Warm feet don't just improve your comfort on the bike on winter training laps. Chilled legs and feet can slow you down tremendously, worst they are a real safety hazard!.
