Because women's barefoot is not beautiful, wearing white sports shoes highlights their temperament and also increases their inner height. This is not a bikini event, so they don't wear high heels. Boys are not allowed to wear shoes because the muscles from the calf to the foot are used as the scoring standard. In addition, in the fitness competition, basically all the sports of boys are barefoot, without shoes, and girls wear shoes (but the specific requirements for shoes are different)
