I like them, but I feel like the elastic waistband around the tummy area creases and folds very quickly. The first time I tried them on was enough for it to lose its shape a bit. Even so, they’re still good leggings — they don’t slip down and they have good support around the waist. However, they’re quite tight around the ankles, and even though I don’t have big ankles, putting them on takes a bit more effort than with other leggings, which is what I don’t like. I’d say they’re true to size. I usually go for an XS in other Adidas leggings, but with these I’d say I’m more of a size S.
