Nike Aeroblade 2016 Rio Olympics Track & Field shorts. These are Brand New but they are made without tags since they are not made for retail stores. They’re made in the USA. There is a liner inside(pictures in the 2nd photo ). The sides of the shorts have a slit especially made for easier movement. Blue and Gold color made I think for Team USA. Also, there are special tiny fin-like blades that cut the wind around the athlete down significantly, called aeroblades.
