The slipper-socks I ordered are splendid. So comfortable and warm.
They wash beautifully. I wear them an awful lot, around the house, and shall be ordering more!

Horray for Heat Holders!

I am delighted to have discovered Heat Holders. I have had my slipper socks for just a few weeks and don't know how I ever lived without them! They are super-warm and the little pads underneath means you don't have to sorry about slipping on a shiny surface. Marvellous product!

Great for layering!

I use Heatholders socks all the time in the winter. I am a long time sufferer of chilblains, and although the socks help immensely, I am never free of them completely. When they a so sore that any pressure from slippers is uncomfortable, I now use a pair of Lites, followed by a pair of originals, with the slipper socks on top! Cosy, comfortable and safe from slipping on my wooden floors. (This combination look particularly good with skinny jeans or leggings. Try it!)

Only thing that keeps my feet cozy.

It's like putting on a cloud 😁

They are lovely and soft every time I put them on I say, wow! But my feet stay cold especially when on a hard floor (wood or concrete) plus slipper socks are just their normal thermal socks (unless I were given wrong ones) packet was same as thermal socks no mention of slippers, bit disappointed my feet still are cold 😔
