Are they comfortable pants? Yes, but I don't think they are designed for girls under 5'5". I'm 5'5", 120lb, normally wear Align leggings in size 4, other leggings in size 6. I tried Groove in size 6, they are way too long for my height, tried size 4 but size 4 is too tight. I'm sure these pants would look great on taller girls, but for my height or shorter girls, I would recommend the short version.
