Wear thermal socks. Socks are the most important part of clothing when it comes to keeping your feet warm. Cotton socks do not insulate your feet well, and you have to wear several pairs to keep your feet from feeling frigid. Thermal socks insulate your feet, because they are made out of insulating fabric, such as wool, silk, polypropylene or a variety of fabrics.
Eat food that promotes body warmth before you ride. Protein-rich foods, such as fish and poultry, and warm soups and liquids increase your body heat from the inside out. While the sustainability of the warmth may not be as long-lasting as thermal socks, you still benefit from the added heat.
Wear rain boots on wet days. Wearing insulating socks is worthless if the socks become wet. Rain boots prevent moisture from seeping inside to your feet, which in turn keep your feet warm. Rain boots are also effective at stopping wind.
Insert toe warmers into your boot. Most toe warmers are activated by exposing them to the air or by shaking them. Toe warmers can be inserted under or on top of your sock. Many toe warmers provide hours of heat, so you're guaranteed warmth even when you're riding down the highway on a cold day.
Clothe your entire body in warm fabrics and wind-resistant gear. Wind-resistant jackets and pants, thermal gloves and a winter hat, in addition to a helmet, help keep your body warm and prevent the warmth from escaping, which means you'll retain the much needed warmth in your feet.
