Heat Holders Original Thermal Socks - Black

Yes, they are machine washable. We recommend following standard care instructions to maintain the loft of the thermal fibers.

TOG stands for Thermal Overall Grade. A 2.34 TOG rating indicates the socks provide excellent thermal resistance compared to standard materials.

Due to their thick, heavy-duty construction, they may feel tight in standard sneakers. They are best worn with boots or loose-fitting footwear.

The moisture-breathing polyester fabric is designed to move sweat away from your feet, though you should avoid submerging them in water as all thermal socks will lose efficiency when wet.

Please check the specific product listing to ensure the size matches your foot dimensions, as the thick material provides a snug, supportive fit.

These socks are high-bulk. Use them with boots or shoes that offer extra room; they are not intended for use with tight-fitting athletic or formal shoes.

Initial shedding of the inner cushion pile is normal for new socks. Wash them inside-out to remove excess fibers and improve comfort.
