These black adidas by Stella McCartney performance track pants are made with partially recycled four-way stretch fabric and cut for a loose fit with an elasticated waistband and cuffs. Featuring a logo at the back, slit side pockets, press stud leg pockets and back pockets, this style has side zips that when open reveal mesh panels. In Stella’s own words, these adidas by Stella McCartney bottoms are made ‘for the ultimate freedom of movement.' Does that mean we can do whatever we want and not what our personal trainer says?
