They seem to be good basic thermal leggings. Leggings with heel openings are hard to find, but I like this type of leggings the best. As for the size I don’t think they are so versatile. I am a size M (38) (EU sizing). Waist 72 cm, hips 96 cm, height 167 cm, weight 60 kg. For someone of larger size the leggings will be too tight definitely. I wish there was a gusset. The seller also sent gift tights of terrible quality, the color of these gift tights painted my hands gray, so I wish there was no extra gift, because it is an unnessesary thing to throw out now. The parcel arrived relatively fast.
I cannot call these goods leggings, rather very warm tights. Not good for tall ladies ( 5’9+ or 176+) - short. Overall, the quality is good, fast shipping. The seller put additional pair of beautiful tights as present. Thank you!
