They are made of advanced thermal yarn with a tog rating of 1.04 & are super soft and comfortable to wear. Our non-binding socks are available in a variety of colors and styles.
  • SUPER SOFT: Our fuzzy thermal socks keep you warm and comfortable. Each sock is intensively brushed so they are sensationally soft and trap warm air close to the skin keeping your feet warmer for longer! The brushed yarn provides high-performance insulation with superior moisture-breathing abilities. The lightweight profile is ideal when wearing tighter-fitting shoes. From work to play, indoors or outdoors, Heat Holders will keep your feet warm and comfortable.

Heat Holders are diabetic-friendly and provide relief for those with cold feet caused by circulation issues. They keep warm air close to your skin & offer support without feeling too tight or uncomfortable. Never sacrifice comfort or warmth, with Heat Holders you can have both!

Our ULTRA LITE socks have a slim profile and lightweight design to comfortably fit in tight-fitting shoes & are great for various activities! Our cozy yet supportive socks are perfect for at home, hiking, work, or other outdoor activities and will keep you warmer than regular cotton & are softer than wool.

From Hawaii to Europe

[This review was collected as part of a promotion.] I live in Hawaii and bought these for a Europe trip this winter so I haven't worn them yet. But I am very impressed with how thin they are yet they still seem to be warm. I'm excited to try them.

Well-received gifts!

[This review was collected as part of a promotion.] These were among the most welcomed Christmas gifts for our daughters and son-in-law. They tried them out immediately and voted them 5 stars.

Toasty

[This review was collected as part of a promotion.] This is a repeat order…They are very warm…and perfect for unloading trucks early in the morning and cold weather. They are thin enough that I can wear them with my regular shoes.
