close-up of two black shoe insoles on a white paper towel. The insoles have a dark, smooth surface with subtle texture and markings. A blue line is visible along the edge of the insole on the left. Surrounding the insoles are various objects on a wooden surface: a black lid, a partially obscured object, a small brush, and a red and silver can. The audio indicates the presence of a machine or motor running in the background.
