    Thermodynamic Run Leggings is rated 4.4 out of 5 by 20.
    Rated 5 out of 5 by from Great run leggings Great fit. Just what you need for these cold days. The fleece lining makes such a difference. I have had many complements.

    Rated 4 out of 5 by from Lovely leggings but not that warm I was so excited about getting these. I bought both the blue and the black, but after wearing the blue was disappointed to find them not as warm as expected. I already have 2 from last year in blue marble in a thicker fabric which I use for walking and they are warmer even if they aren't as pretty.. Am wondering whether to return the black even though I love the look of them. Fit is good. I am 5'11' and between sizes 18 and 16 as losing weight. A large seems a good fit. Only reason for not recommending is that they are not as warm as hoped.

    Rated 2 out of 5 by from Really comfortable but the colour cracks I bought these leggings last week and was so excited to go running in them for the first time. They are really comfortable, flattering and they keep your legs warm in this freezing cold! I've worn them for three runs already, but I'm disappointed to notice that the blue stripes coming down the thigh have already started to crack. These leggings were a real investment for me - I'm a big SB fan, but I usually only buy items in the sale - so I'm feeling a little bit upset.

    Rated 5 out of 5 by from The best winter leggings I have found by far These are best winter leggings I have found by far! I love them... just the right fit (I bought them online based on the sizing chart) and ideal temperature-wise for very cold morning and evening runs (0-8c) They wash well and dry quickly. I could not be happier.

    Rated 3 out of 5 by from Not as warm as expected I loved the look and feel of these leggings and I had high hopes for them as I get extremely cold thighs and butt whilst playing evening outdoor tennis in the winter, but they didn't keep me much warmer than regular leggings,even when used as a base layer under tracksuit bottoms,I'm not sure why they didn't work for me as other reviewers loved them.

    Rated 5 out of 5 by from Multi-purpose and super cosy I wore these for extra warmth while watching Scotland play New Zealand at Murrayfield, and as a thermal layer for hiking up Ben Lawers in a snowstorm. Utter perfection. Warm while stationary or active. They sit perfectly on your waist and don’t slip down at all. I love them.

    Rated 5 out of 5 by from So cosy and comfortable, look great I love these leggings - I thought the black/silver design would be more flattering but actually the blue/black looked better. I have had loads of compliments on them (especially worn with blue pleat back hoody). Love the fleecy lining. I did have to size down from usual S (I am size 8-10) as the thermal fabric means they aren't as tight fitting as other SB leggings, the S felt a little baggy and unflattering! The one thing I am wary about is the blue lines deteriorating, they are cracking after only a few wears and washes. Will be fine if that stops as it is but will look awful if it continues.

    Rated 5 out of 5 by from LOVE I needed a pair of warmer running tights and decided to try these. Not disappointed. Love them First of all they go on easy and feel like scuba material and are very soft on the inside. The medium fits perfectly(size8-10 in jeans usually) although the legs are on the longer side which in the winter is a plus. Wore them this morning for my run. It was below freezing and my lgs were nice and toasty . They were not overheated and never did I have to pull them up. The tights stayed in place. Hoping for a sale to grab myself another pair .. These are going to be my go to running tights in the cold weather.

    Rated 5 out of 5 by from So cosy! I bought these in the previous colour way, black with neon orange and white panels. I love them! They’re so cosy I don’t want to take them off after my run. Nice and warm, but not so thick that they’re unflattering, with a lovely fleecy inner. As always with SB, the colour panels are super flattering, and I always get loads of compliments when I wear them. I’m a fit size 14, and I find the L a little on the roomy side in the leg, but I think the M would be too tight around the waist (that’s what having kids does to you!) Looking forward to my next outing in these lovelies, they’re my new favourites.
