1. Take out the original insole size in the shoe. Find cloth, jeans and insoles to reflect the pattern, take out scissors and cut them to make them bigger. Double-sided adhesive tape is attached to the volcanic magnet insole, the side contacting the foot is attached, and the reverse side is placed.

2. The position of the volcanic magnet insole is cut along the grain. Jeans have porous fibers and absorb more sweat. The humidity in the shoes can prevent odor, prevent skid and keep warm. Volcano magnet insoles can be placed inside shoes.
