The high, curved part of the foot between the heel and the ball. Also refers to the raised part of the insole of a shoe that supports the arch of the foot.
About Cushioned:
Cushioned shoes, or neutral cushioning shoes, are shoes designed for runners with normal to high arches who tend to underpronate. Cushioning shoes generally have a padded midsole with layers of extra cushioning in the heel and forefoot that provide better energy return to the body when compressed while helping absorb heel shock and encouraging a more natural foot motion.
About Insoles:
Insoles are foot-shaped pieces of material that are inserted in footwear to give extra comfort and support to the foot. Insoles may also function to assist in the proper fitting of shoes.
