Bought to wear casually but also for running and exercising I absolutely love them so far. They are so comfortable, very supportive and flattering to wear. They look good and don’t fall down like other brands. They don’t loose shape and stretch as required and wash up well. The size is a good match. Although I’d never heard of OSO these are fast becoming my go to for my running leggings. Great value for money too and sustainable at the same time.
