Invisible but still cover main area of foot

Really nice. Like that they go a bit further up the foot compared to others bought, making them more comfortable with trainers. Gel pad on the heal adds to comfort and does not allow sock to ride down .

Trainer liners that are brilliant

Yes, I recommend this

These trainer liners are brilliant. The silicone finish inside the heal grips very well and they are so comfortable. I don’t know what I will do when it gets too cold to wear these and I need to wear proper socks. I love the size range, the 3 - 5 fits me well as I am just about a 4 and quite often I find socks too big for me unless I buy childrens

Love these for my trainers. This time when I opened my parcel I noticed there were only three pairs instead of 4 and there were dirty marks on them, disappointed.

Soft & don't slip off your heel!

Yes, I recommend this

Really pleased with these trainer liners. Sizing is spot on, they are good quality (nice and soft) and, most importantly, they don't slip down inside your shoe! I have purchased a further set of 4 pairs. Highly recommended.

Sized up.

Yes, I recommend this

These are great socks but over time they get tighter in the wash so had to buy 6 to 8 for 5 and half shoe size. I wish you still did small, medium and large! Photo is inaccurate as these only come in black or white now not multipack?

Brilliant idea.

These are perfect trainer liners. They are indeed invisible, they stay in position and the cotton content means they keep feet cool and comfortable

Comfy and stay put!

Yes, I recommend this

Love these to wear with trainers and a skirt. Have bought other makes in the past and they don’t stay put and wrinkle under foot having fallen away from the heel causing discomfort. These trainer socks stay put and are comfortable to wear. Will be buying more.

Unable to use

No, I don't recommend this

They slip off at the back so I can’t wear them. I really hoped these would work given previous reviews.

As described

Yes, I recommend this

Not to say really except that they are as descibed. Nice thin trainer liners that so far seem to stay in place. My only complaint and I know the answer will be something to do with hygiene but you do need to try things on and plastic barbs through the centre of socks makes this impossible. Fortunately as a borderline size in footwear, I was able to try on a friends before purchasing.

Great trainer socks. The rubber insert at the heel helps the socks stay in place. I have had several Pairs over the years and they wash well.
