This Kicking icon is made in Material Design style developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 4,300 icons, all in the same style and quality.
This is an image of a person kicking. He is standing on one leg, with the other leg outstretched in a kicking motion. His body is tilted away from the kicked leg, with the back arm pointed downward and the front arm bent upwards.
