Great socks

I do a little extra present for everyone at Xmas on Boxing Day & attach via raffle tickets to crackers I’ve made myself. As the men I bought these for are middle aged to elderly & go to football matches I thought these would be ideal to wear on match days as the weather gets warmer. They are lightly thermal instead of the heavier thermal ones they usually wear. Haven’t had any feed back yet but I’m sure it will be good as they all wear M&S socks normally.

Good to have effective thermal socks which are also light and do not result in a tight fit in my shoes

Great winter socks

Originally posted on marksandspencer.com (UK)

Excellent socks, very warm but remarkably thin! As warm as the best thick Nordic socks that cost a lot more. Equally at home in a shoe or a boot, smart or casual. No more cold feet , well worth the money

Definitely warmer for colder weather

I bought these for myself as M&S don’t seem to make this thickness of Heatgen socks for women any more. I’m a size 6 and after washing/tumbling they fit nicely. Only gripe is, the elastic in the top can give way very easily. They still stay up but not as well. I like the material - very slightly thicker than a cotton sock but not bulky like most thermal socks.

Brilliant, a lightweight, fine knit sock with thermal capacity. Much more comfortable than usual thick thermal socks and well priced.

These are good. A small improvement on ordinary socks and not too thick and cumbersome. Good value too.

Thin enough for two pairs, but thick and warm enough to be worn alone. Kept my son's feet warm and toasty whilst we walked round a chilly, snow covered New York!
