As many of you keep telling us, our Sleep Socks were one of our favorite products ever!  For the first time in 2 years we now have them back in stock!

The sleep sock was designed to leave unrestricted circulation around the cuff - a top rising softly just above the ankle with no extra spandex ... just the natural stretch of the terry loop construction.  It added the needed insulation to keep your blood supply in the feet comfy .. in bed, walking or even with shoes or slippers. This version of the sleep sock is a yak/nylon yarn blend.

They were warm, comfortable, durable and we have it on good authority that they actually saved several marriages.

  • Stretch terry loop construction on inside, flat knit outside
  • Loose cuff bindoff top of sock, less restriction on ankle
  • Natural brown Yak fiber (no dyes)

Sock Sizing

Socks should fit as well as any of your other garments. The heel should sit on your heel and not under it as in a sock too small, nor half way up your Achilles as in a sock that’s too large. Socks should be flush against your foot with no extra material sagging. The toe seam should lay flat across the top of the toes.

Sock Heel at Your Heel
The sock heel should sit on your heel, not under it or above it.

Flat Toe Seam
The toe seam should lie flat along the top of your toes, not above or below.

Taut Across the Foot
Socks should be taut across your foot with no sagging material.

Unexpected favorite thing

I bought these socks for my wife unexpectedly and for no reason. I let her open the package, cause I put her name on it. She was so confused as to why I bought her socks, but then she put them on. She melted right there where she stood. She almost refuses to take them off. I’ve had to tell her that it’s time to wash them. She’s says it’s the most comfy thing she’s ever had on her feet. Now I need to get myself a pair. Thanks Ron!!

Sleep Sock Are Warm and Comfortable

At last my feet stay warm all night. These socks fit well and are soft. I no longer wake with cold feet. The design of the upper sock leaves no pressure indentations on my ankles.

I have tried many types of socks for sleeping and these are by far the best. After using for a month I no longer think about about cold feet.

Great sleep socks

I wore them to sleep as soon as I received them and they work so well. They are not tight around the ankle but still stay on my feet. They are thick and keep my feet warm and toasty. I'll will get another pair if I can't hint to get a pair for Christmas.

David G. (Torrington, US)
Wife loves them!

My wife commented how much she loves the sleep socks, but only has 3 pair. I gave her 3 more pair as an early Christmas present. We are up in the NE and it’s starting to turn cold.

S. K. (San Antonio, US)
Best sleep sock

I wear sleep socks year-round. I have been looking a long time for non-binding sleep socks. I am so glad I found these socks. They are non-binding, the height is perfect, and my feet are pleasantly warm! I highly recommend these sleep socks.
