Cosy little socks

Yes, I recommend this

Lovely little trainer socks keep your feet warm. A little pricey but worth it. Only gave 4 stars because they weren’t as Black as previous pairs I’d purchased

Quality soft trainor socks

Yes, I recommend this

Bought a pack of three and initially they looked great. Nice stylish design and soft, but one pair came up very small! Having cut the tag I decided to keep them and give the small pair away. Thus the low stars. Still think they are good socks
