Insole

Abstract

Disclosed is a insole arranged on an upper surface of an innersole in a shoe. The insole includes: an intermediate supporting portion 41 coming into close contact with a center portion of a foot sole, including an arch, and having a plurality of elastic protrusions P formed on a lower surface of grids L defining grid-type thru-holes; and a rear supporting portion 42 extending from the rear end of the intermediate supporting portion 11 to a heel of the foot in order to make close contact with a rear portion of the foot sole, and having a plurality of stationary protrusions P′ formed on the lower surface of the rear supporting portion 42 to protrude downward. The insole can improve air permeability through the thru-holes, and in addition always makes close contact with the foot sole through elastic protrusions formed on the lower surface thereof so as to buffer impact on the shoe. Further, the stationary protrusions formed on the lower surface of the insole are stuck in the innersole, thereby preventing movement of the insole inserted in the shoe.
