The benefits of socks

Whether you use your bike for daily journeys or racing in competitions it takes a toll on your feet. Pedalling can result in rubbing, which, coupled with perspiration can feel very unpleasant. The cold can also make cycling uncomfortable if you are not properly protected.
These B'Twin 500 socks offer the warmth that's essential during regular cycling in cold weather thanks to their blend of Merino and Thermolite fibres.
