Ideal for winter

Yes, I recommend this

I couldn’t get through winter without these socks, they’re a good length and much better than ankle socks (in my humble opinion). The socks are not too thick and not too flimsy, ideal to wear underneath jeans and trousers. I sincerely hope they’re available for many years to come.

Winter Ready Socks

Yes, I recommend this

Bought ready for the winter, only classed as thermal 1, but will be ideal until thermal 2 becomes available. These come nearly up to the knee, and the heel in quite strong. Nice to have plain colour thermal socks.

Comfort and ease

Yes, I recommend this

Brilliant! They are so comfortable that I wore them in bed. No more restless legs. Easy and for support they are soft, fit well, and like all M&S items, wash and dry well. I'll definitely get some more. Great value for money too.

Padded feet!

I bought these at the same time as the other long thermal socks and decided that they weren’t as good as the other ones. They have Padded feet, which I’m not sure we’re going into shoes. Also, the leg section is thinner and I’m not sure would be warm enough. I returned them.

Wonderful

Yes, I recommend this

The cushioned foot is so comfortable, cosy and warm that I had to buy more. My feet are size 6 and I always buy 3-5 from M&S as 6-8 have always been too big. I have skinny legs so they are not too tight.

Disappointed .

Yes, I recommend this

I always purchase these for my sister who likes to wear them with her boots in the winter months .Although she loves the softness and they wash well .The recent ones have thinned very quickly about the toes and heels. For this reason l have only given them 3 stars.

Brilliant Thermal Socks

I purchased these for my upcoming cruise to Norway, which will be very cold & I need some socks that are not only warm but comfortable.. These socks have a padded sole which is excellant cushioning for the bottom of my feet.

Thermal socks that make a difference

Yes, I recommend this

Knee high socks that stay up -They are a fine knit so the socks don’t feel bulky when worn in boots or shoes and they dry reasonably quickly .Thermal quality good and make a difference when worn compared to my usual socks
