Great Idea

Yes, I recommend this

Love these leggings. They’re great for wearing with boots as the underfoot strap keeps the leggings nice and straight on the legs. Great idea M&S as they take me back to my youth.

Good all-rounder

Yes, I recommend this

Quite handy leggings, stirrups make sure they don't ride up, wearing for walking as good with waterproof over trousers if necessary or reasonable warmth if worn alone. Size down for closer fit, also handy for outside work at home.

Heatgen Leggings

Yes, I recommend this

I am so happy with these leggings. They are not too thin or too thick and are lovely and soft. The straps are great - I wear these under jeans/trousers and they don’t ride up. They are quite roomy. I will get another pair but will go down a size. Definitely worth the price.

Nice fit and style

Yes, I recommend this

Like the style and fit of these especially the foot strap, but after only one wearing the material at the top of the leg is starting to “bobble”, but I suppose at this price I was expecting too much. The material is thinner than other leggings but seem to be warm.

Lovely thermal leggings, not quite as warm as I had hoped though. Also had to change for a smaller size, so slightly towards the larger fitting I would say, but great length. I am 5’4” and the length is great on me.

Impressive lightweight thermals

Yes, I recommend this

Impressive lightweight thermals. I wore them under jeans to watch a football match on a freezing cold day and they kept me warm. They seem to be true to size, maybe with a little room to spare.

Love them

Yes, I recommend this

Bought to wear around the house on cooler days. Love the under foot straps which help keep them in place and not twist. Lovely brushed, soft cotton and lovely and warm. They did lose a bit of thickness in the wash but still great leggings.

Super soft and super warm

Yes, I recommend this

Incredibly warm and soft. Can’t believe how warm they are when they seem so thin. Stirrups are great. They do fit big. I sized down to a 10.

Good and not so good 😊

Yes, I recommend this

The fabric has a lovely feel and the fit is great but I was disappointed in the thinness of the fabric, also wasn’t keen with the sheen on them. However with a pair of black opaque tights underneath it helps and they then look better.

I'm 169cm, 62kg. I bought the L size. I'm very pleased. The design is great. I don't like leggings. This is very comfortable. And my ankles don't get cold.

Good quality base layer at a reasonable price.

Yes, I recommend this

Not what I was expecting. I chose them as they had stirrups which I prefer for winter leggings under boots and it saves me sewing my own on. However, when they arrived they were marked as a base layer. Not really suitable to be worn alone as leggings. Having said that I kept them as they do fit nicely under trousers as they're not too thick and give an added layer of warmth. The fit was quite generous but not massively so though I could easily have got away with a size smaller.

Would love these in navy

5* Material quality thick and warm 4* as Material is shiny & only 1 colour available Would love navy in these stirrup leggings. Fit is good though form fitting so I suspect some may prefer a looser fit and go up a size. Not washed yet so can’t comment but don’t anticipate any problems

Great stirrup leggings

Yes, I recommend this

I am always on the lookout for stirrup leggings, especially at winter time. Stirrup leggings make life so much easier, they stay tucked into boots and looking smooth. These leggings are quite lightweight but warm, and they have a nice finish, so they are smart enough to be worn by themselves. I will be getting more!
