Runners often use running tights in addition to running pants or running shorts.
Running tights are meant to lend further support to your legs by helping absorb some of the muscles' energy impacts from pounding and stretching.
And of course, running tights are also intended to keep your leg muscles extra warm so that they remain supple and loose. But if you wear running tights, you of course need them to be of the highest quality so they are not constrictive on either your legs or at your waist.
They also need to be made of very durable material given the wear and tear a regular wearer of them is going to expose them to.
