Product Description: Flat insole Silver ions are woven into the surface, providing antibacterial and deodorizing functions. Beneath the surface fabric, blue memory foam sponge is sandwiched, which also absorbs impact. The underside is made of mesh, which is highly breathable and designed to prevent stuffiness. The human foot has three arches, and if their balance is disrupted, it can be one of the causes of stiff shoulders, lower back pain, and knee pain. Insoles are designed to support these arches. They fill the gap between your shoe and your foot for solid support! Protect your feet as an athlete, power up! Speed up! Level up! Furthermore, since there is no gap between the shoe and your foot, it also helps prevent injuries, such as sprains. How to set up: Remove the insole that originally came with your shoes, place the new insole on top of it, and draw a line with a ballpoint pen on the parts that extend beyond. Cut along the line with scissors, and replace the original insole with the new one. If you have any questions, please feel free to ask. Thank you very much.
