These are the perfect leggings for tennis. They have multiple pockets for ball storage, both a regular pocket and a slip-in pocket on each side. These are great for left-handed players as many designs only offer pocket(s) on one side of the garment. These adidas leggings have an internal tie waist which keeps the leggings feeling secured in place. They are full length leggings which suit my 5ft7 frame. These were really a steal as it is very difficult to find leggings specifically designed for tennis, as many other leggings which host pockets tend to be designed for phones instead of tennis balls. Great work adidas.
