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).

Flats are more lightweight than regular running sneakers so they do not last as long. Their soles get worn down faster and therefore they have shorter natural lives.

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