Long thermal socks

Yes, I recommend this

As expected, nice and long, good price point. Not much colour choice. Will be useful. Not worn yet.

Warm socks

Yes, I recommend this

I’ve bought a few pairs of these over the past couple of years. They really do keep my feet and legs warm during winter. Wash and wear well.

Not stretchy

No, I don't recommend this

Bought for elderly mother to keep her legs warm with skirts. Though the feel of them was lovely there was very little stretch. Ended up taking them back for a refund. Unfortunately I had opened 2 of the packs so have to keep them.

Nice but narrow.

No, I don't recommend this

Ordered the wide fitting for ease putting on as I have sprained my back. Was shocked to find they were no different at all in size, quite tight really around the top and my legs are not “wide”, take a size small in tights. Unhappy with the fit as the sock are a lovely knit and soft.

Just what I’ve been looking for !

Yes, I recommend this

These are great socks , knee length so don’t show bottom of legs when sitting down in trousers ! They don’t grip your legs too tightly but don’t roll down either ….amazing 😁, Very comfortable on the soles of feet as well

Warm socks

Yes, I recommend this

Love these socks but really wished I could get the wide fit size online. I have poor circulation in my lower legs and these are just perfect under my leggings to help keep my legs warm. However, I do find with M&S garments etc they are very skimpy with material IE if you are a size 18 go up a size to ensure a comfortable fit.
