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 and value.

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.

Good trainer socks

Bought this by mistake as they are described as trainer socks. No good to wear with loafers.

Great Value,

Yes, I recommend this

Not the finest quality, but good enough. They keep your feet cool, stay hidden, and remain in place. The star of the show is the little rubber section on the heel. Really impressed how this holds everything in place .

Good quality, fit and price.

Yes, I recommend this

Great quality and fit, these are far and away the best style of these socks I have bought. They stay on your feet and don’t slip off whilst you are wearing them. They are cool in the hot weather and fit really well. I’ve ordered some more.

Much better sizing!

Yes, I recommend this

Always buy these trainer liners but I do find they shrink a bit. So decided to try men’s which are exactly the same only bigger and will continue to buy these in the future.

So far so good!

Yes, I recommend this

I chose these 6 - 8.5 over the womans 6 - 8 as I always find the womens small for me and this allows for any shrinkage. Added bonus you get 1 more for the same price. V. good as almost invisible. Yet to wash and wear them a few times to see if the silicone remains "sticky" as it is this that makes the difference with the liner staying in place!
