Socks with a tog rating...

Who would have thought that socks could have a tog rating.  On those chilly winter mornings, we can all have moments where we pine for our lovely cosy, warm duvets. My solution.....Heat Holder socks with a tog rating of 2.3.  It's not the same as being completely enveloped in a duvet, but if you get cold feet you know how it just affects you all over.

There are so many things to say about thermal properties of socks, so for now let's look at the tog rating.  Most of understand the higher the number, the better the warmth, but why aren't all thermal socks able to do the same thing as Heat Holders? Whilst there are varying standards and qualities to thermal socks, an average sock can rate approximately 0.89 as a tog rating.

The tog rating is given based on how much warm air is held in the fabric.  A loosely knitted product, with a short pile is not going to achieve as well as one which has a longer pile or bulkier yarn.

• Heat Holders have an extra heavy bulk yarn - which boosts the thermal qualities but doesn't make the sock heavy to wear or to move around in.
• Long pile cushioning makes the socks comfortable and adds to the thermal tog rating.
• Finally, the inside of each sock has been brushed so that even more warn air can be trapped by the yarn for longer. 

My office has a very cold floor, which even through boots sometimes leaves me chilly, so the Heat Holders are off to the office today, for some more road testing. I'll report back later!

Blip....the tog rating scales was developed by the Shirley Institute in Manchester in the 1940's.
