Great but small!
The product functions perfectly - my toes are indeed very warm. I wear the socks for cycling and on occasion whilst walking my dog, but 99% of the time they're for cycling and I have certainly noticed that my feet stay warmer for longer. I'm a bog standard size 5 and I bought the appropriately sized socks for my feet but they come up very small (as in they only just fit), I didn't have time to return/replace them because of the weather, but should I buy another pair, I would go a size up (medium I think). The socks wash well. Overall I am satisfied with the product.
