While socks are one item of clothing that most people will likely have an abundance of, it’s worth investing in some cycle - or running - specific ones. These will utilize materials, designs and features that take into account the demands of exercise, and may also offer additional protection against wind and rain, helping to keep your feet dry and comfortable in cold conditions. Meanwhile they will also be made of materials that offer much better technical performance than standard cotton socks.
There are different types of socks designed for optimum performance under various conditions, and the type you choose will largely be determined by when you want to use them and what performance priorities you value. A thick, waterproof and thermally insulated pair of socks, for example, will help to keep your feet dry and warm in the winter, but will be overkill in the summer months when you need short, lightweight socks that help to keep your feet from overheating. You may well find that a selection of season-appropriate socks is the best option.
