Invisible socks

Yes, I recommend this

Bought these for my husband to wear with his new trainers. They come up higher on the front of his foot, but are still invisible.

Comfort at last!

Yes, I recommend this

The ladies 5-6 socks are so very small and tight, so I sized up to mens 7-9 and they are perfect for my 5.5 feet.

More Colours please!

Yes, I recommend this

More colours please! I purchased these to wear with leather loafers - not trainers. Please can you introduce more colours that will coordinate with your extensive range of loafers.

The best of any I've used.

Yes, I recommend this

These socks are very good. They fit well and wash up great. They have retained their elasticity and the heel insert reduces the likelyhood of the sock walking down your foot and hiding in your shoe. This does not mean it doesn't happen after extended use, simply that they have more resistance to creeping than other socks I have tried.

Too small

Purchased the 9-12 size for my husband. Unfortunately have to cut packaging to check size and they are miles to tight, he is size 11. Can't return and wish I had bought the larger size. Disappointing as good quality.

Love these! Finally some trainer/invisible socks that stay on my feet all day. There's a good rubber pad at the back that holds them in place.

Great quality product. Worth paying the little bit extra compared with others. They are very comfy and the heel grip secures them for all day use.

Sizes need printing

Yes, I recommend this

OK, but it would be so helpful if the size could be printed inside all single colour M&S trainer liners and socks as it's so hard to tell a 9-12 black trainer liner from a 5-7 black trainer liner when they've all been through the wash together. Also the biggest size could be a bit bigger.
