Good socks that stay put

Yes, I recommend this

Lovely socks. Bought the men’s ones as they have a grippy piece of rubber in back and I found they stayed put better than the women’s ones.

Comfy stay put

Yes, I recommend this

These socks are perfect for my husband, he wears them for golfing, as they stay put and don't come off the back of your feet.

Not great quality

No, I don't recommend this

Poor quality, developed holes within a couple of wears. This is the second time I have bought them, i thought that i would give them another go and buy a bigger size. I thought that maybe they had developed holes because they were too small, however the new bigger size have also developed holes in the toe. The fabric is too thin. I love the idea of the silicone to keep them from slipping, just wish the fabric was thicker.

Summer sock

Great socks for summer, especially if you don’t want to show any sock. Comfy, and good quality material. Very much recommended.

Very comfortable

Yes, I recommend this

Very comfortable and they stay in position for me. I bought the biggest size possible as socks always seem to come up small and I hate having squashed toes.
