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 tend to be of less substantial construction and so have shorter natural lives. But this is mitigated by the gentleness of ground contact of the runners that use them.

They are mostly sold as "for use up to 10k", but are used by some runners at any distance, including ultramarathons.[1]


Racing flats have only small or no heel lift and little padding or support. They allow a prepared athlete to use their natural foot strength, elasticity, and proprioception to run quickly.[2]

A typical flat consists of just a nearly flat sole, and a minimal upper to hold it onto the foot. Frequently the thin insole is glued in place to reduce movement and weight. The uppers are often mesh so that moisture can escape, even on crosscountry variants.

Racing flats vary in weight, ranging from 230g (7-8 oz) down to the mere 70g (2.46 oz) of the women's New Balance 5000.[3]


Because of the lack of support and cushioning, racing flats are typically not recommended for use by the uninitiated because of their lack of lower leg/foot strength. But as an athlete progresses with their training they will be able to make full use of them.

Before the invention of the Nike shoes in the 1970s, everybody used flats because that was the only shoe available for road running.[4]


Studies[5] have suggested that some running injuries can occur as a result of the significant arch support and cushioning found in "traditional" running shoes. As a result, a growing number of runners train and race exclusively in racing flats, other minimalist shoes, or barefoot. This is known as minimalism. It is also useful to improve the muscles and the running technique.


Popular examples of racing flats include the Saucony Type A6, Saucony Fastwitch 5, Merrell Road Glove, Nike Zoom Streak, Nike Zoom Marathoner, Nike Lunaracer, Nike Flyknit Racer, Nike LunarSpider, Nike Mayfly, Adidas Adizero PR, Adizero RC, Asics DS Racer 10, Asics Piranha SP 4, Puma Taper, Mizuno Wave Universe 5, and numerous others.
