Shoe sole with loose fill compartments seperated by arch support

Abstract

A shoe is provided with an outsole that contacts the ground, an insole upon which a foot rests, and a midsole located between the outsole and the insole. The midsole cushions the wearer's foot by providing a loose fill material in a front compartment on which the toes and ball of the foot of the wearer rest and a heel compartment on which the heel of the wearer rests. The front compartment is divided into at least two sub compartments to keep the loose fill evenly distributed. The front compartment and the heel compartment are separated by an arch support section of the midsole, which provides relatively rigid support for the arch of the wearer's foot.
