In this age of retail therapy, buying the right clothes is supposed to make you feel better. Can the right clothes also make you run faster? Nike seems to think so:
The Nike Swift System of Dress [increases] aerodynamic advantages on key parts of the body. Socks, gloves and arm coverings - an entire system of dress - were developed by Nike so sprinters could run faster. For example, the Nike Swift gloves and arm coverings have dimpled fabrics like a golf ball to cut wind resistance and allow arms to slice through the air faster. In testing, the design team found that compared with bare skin, the gloves and arm coverings reduce drag by 19 percent and the socks by 12.5 percent.
