I have long suffered from icy feet when riding in the winter, and even during autumn and spring. I’ve tried many solutions – two pairs of socks, socks plus polythene bags (yes, seriously!) – and I always wear overshoes. But my feet have remained icy cold. However, I’ve been wearing a pair of Defeet Wolly Bully 2 socks and I have to say they are the best that I have tried, keeping my feet warmer, for longer. They don’t completely solve the problem on longer rides, but yesterday my feet were okay until quite a long time into the ride.
If you have the same problem then have a look at them.
