Racing flats

Racing flats or simply flats, are lightweight athletic shoes designed for long distance track and field, cross country, and most often - road races. They differ from normal training shoes mainly by the lack of a substantial heel (hence the name). They are also a great deal less durable and typically last half to a quarter of the distance of a normal training shoe (125-250 miles or 200-400 kilometers). The removal of the heel in racing flats has 4 principal effects: weight reduction, better foot to ground power transfer, providing less support and giving less cushioning. These features allow a runner to race more efficiently.
