Insole - Insoles

An insole is the interior lining or padding that runs the entire length of an athletic shoe and sits beneath the foot when worn. The insole is the separation between the sole construction and the foot. The insole offers slight cushioning and support for the foot and helps to enhance the cushioning devices of the shoe itself. Special insoles called orthotics can be bought to replace the insole that came with the shoe, offering elevated support for people whose feet tend to overpronate. Orthotic insoles are great for runners and other athletes because they control the angle at which the foot lands.

An insole is meant to contour to the shape of an individual's foot. The factory insole inside an athletic shoe is typically a general shape, and does not tailor to the individual needs of each wearer; therefore orthotics may be necessary to provide control for those people whose feet are not of a neutral angle. Insoles are a necessary element of an athletic shoe not only because they provide a barrier between the midsole or sole of the shoe and the foot but also because they keep the foot dry due to the perforation necessary for ventilation.  Insoles can be used to:

  • Provide cushioning
  • Provide stability
  • Control the shape of the shoe
  • Control bacterial growth
  • Control the moisture produced by the foot

Insoles are usually removable and replaceable, but will last longer if you wear socks, which absorb most of the moisture produced by the foot. Insoles are a necessary component of a shoe for comfort; without them, even the most expensive shoe would hurt your feet.
