Rated 2 out of 5 by SheRuns_29 from Comfy but weak stitching If you need some leggings for a cold winter walk, look no further! These leggings are incredibly comfy and will keep you toasty all day long. However I wanted a pair of leggings for early morning winter runs and unfortunately these do not measure up to the standard of the Power leggings, nor the Zero Gravity (I have multiple pairs of both, and they haven’t let me down yet). The stitching on these mean that there isn’t so much flexibility. I had to take them back after trying them on- which was a shame.

Rated 2 out of 5 by Nic99 from Stitching coming undone already Disappointed! Bought these to replace my old SB thermodynamic leggings which I’d had for years and loved, but the stitching on these has come undone after wearing them only three times.

Rated 5 out of 5 by TrendingInTribeca from Winter Running Gear Bought these to brave the cold, brittle, windy NYC winter weather. These do not disappoint! I bought the matching top too and the set is so cute. Makes me feel stylish while keeping me warm on my winter runs! The fleece lining inside is soft and warm, but not too thick. SB always has the best quality — their garments are worth every penny! I found these to run TTS if not even slightly large, but I wouldn’t necessarily size down.

Rated 5 out of 5 by Mwils12 from Flattering, warm and versatile I have been wearing these leggings non-stop recently in the colder weather. I found them to be the perfect balance, warm enough to walk in but not so warm I couldn't run in them. The inside is so soft and comfortable. I had seen some negative reviews about seams coming loose after washing but have not had any problems myself - they came out good as new! #teamsweatybetty

Rated 5 out of 5 by Chitchatcath from Best dog walking leggings Bought for dog walking. Initially when I received them I thought they wouldn’t be warm as the fleece is quite thin but they are really cosy So comfy, hold you in in all the right places & the high waist stays put. Expensive but worth it & I'm sure I’ll have them for years. I’m size 10/12 5’4” & bought small 7/8.

Rated 3 out of 5 by Shellrunsthings from Thermodynamic running leggings I was so excited about these...I adore sweaty Betty and save up for the gear as love it so much, however in the first run these bobbled a bit at the thighs and thread came loose at the ankle. Ive worn them 5/6 times now and the bobbling is extreme - washed as instructed. I don’t expect this from such an expensive product. I won’t be sending back but it has made me consider sweaty Betty leggings in the future. Maybe my larger than average thighs but still...

Rated 5 out of 5 by Lindz18 from Toasty Thermo Legging I buy every colour of these that come out. They are warm for running and they allow you to move in every direction. My love for them has increased this year with the addition of the side pocket. They wash brilliantly and are just my go to leggings on a cold day. #teamsweatybetty
