Abstract: An inner sole for a shoe, the inner sole having a heel portion, a mid-area portion, a metatarsal portion, a metatarsal/toe transition portion and a toe portion. Force absorbing, compressible blisters, each having a perforation, extend across the heel portion, the mid-area portion and the metatarsal portion. There are truncated blisters in the metatarsal portion and no blisters in the toe portion. Orifices are disposed between the blisters and truncated blisters, and are in the toe portion. The orifices dissipate moisture from a user's foot. Also disclosed is a shoe arrangement including the foregoing inner sole, and layers including a breathable and/or moisture permeable layer and a fluid-absorbing layer.

Abstract: A process for producing an inner sole including a sole base and a plurality of blisters integrally formed on the sole base and extending away from the sole base, the process comprising the steps of preparing a mold with a recess for forming the sole base and the blisters, the recess having a number of projections on a first area and clearances for forming hollow spaces on an opposite second area, preparing a flexible elastic material, introducing material into the mold to form the sole base with integral blisters, and removing the inner sole from the mold.
