What is a Thermal Sock?

  • A thermal sock retains heat.
  • It can be worn over your regular socks to keep you warm on cold days.
  • Thermal socks often have an extra layer of fabric or insulation around the foot.
  • They are thicker than normal socks but not as thick as booties or slippers.
  • These types of socks are great for wintertime! However, thermal socks are made with wool, bamboo, or cotton, which all have excellent insulation properties.

Do Thermal Socks Really Work?

  • Yes, they provide Ultimate Protection against cold!
  • ​​People don’t always think about their feet being cold, but they might start to feel it when the weather drops below freezing. The key is insulation, and these socks score great on that!
  • These particular foot coverings work by trapping your body’s heat and using it to keep you warm during even the most extreme conditions.
  • Therefore, for the ultimate durability and comfort, invest in some cable knit socks.

Does Wearing Two Pairs of Socks Keep Your Feet Warmer?

  • They Don’t!
  • Two pairs restrict blood circulation – Shoes and boots are designed only to fit your feet and a single pair of socks.
  • When wearing too many layers on top with tight-fitting shoes or boots, additional pressure is put onto our feet, restricting circulation. This limits blood flow from reaching our toes and allows them to become cold quickly.
