Running shorts

Running shorts are designed to facilitate comfort and free movement during exercise.

Polyester is a common fabric in running shorts and makes it comfortable.

[citation needed] Many running shorts have a seam cut up the side of each leg to enable freer movement.

Nonetheless, some runners prefer longer shorts because they cover a greater portion of their legs.

Like 1/2 split seam shorts, hot pants do not encumber leg movement.
