Very warm but actual sizes vary a bit

I am very pleased with my new socks, so much so that I have now purchased three pairs. They are incredibly warm. However, the second pair of size 6 to 11 socks that I purchased were noticeably larger than the first pair I ordered and that is why I have only given four stars on this review.

Quite good, but...

They are really warm.
But the seams at the forefoot are so thick, they are barely wearable.

We are sorry to hear of the issue, our customer service team shall send you a private message to resolve.

Great socks.

Excellent product. Keeps feet and legs warm and long legs come to just below my knees which is better than shorter socks which can hurt my lower legs.

Sock it to me!

My very best Christmas present ever was a pair of hot socks from my wife. I refused to take them off until a second pair arrived. I sent a pair to my Bro’ - he loves them, too. And, because he lives in Norfolk where it’s very cold, he’s keeping his on. I also recommended them to my pedicurist, but her son has
nicked them. So now you’ve started a crime wave down here.


Gift for my dad he loves them. He now has super warm feet whilst walking the dog.
