When choosing a pair of pants/capris/shorts to run or jog in you’ll want to find something that creates as little friction as possible and avoid items of clothing with a lot of excess material and should opt for something form fitting through.
The reason for this is you’ll want to run as quickly as possible without your clothing hindering you, hence looking for good quality leggings, such as the Wear it to Heart leggings, that will cause little friction against your legs and preventing a rash from the constant movement. And you’ll want to avoid the mishap of tripping or getting your foot caught on your pants.
Most leggings designated for running or jogging are meant to be worn skin-tight and are designed to improve comfort during such a rigorous workout such as running. Another benefit of most running legwear is the fabric is able to draw sweat away from the skin to prevent chafing and helps cool you down during your workout rather than keeping all the heat against your skin.
While there are a lot of styles to choose from try to stick with something form fitting and tight to ensure your workout is a comfortable one.
