Shoe with breathing sole, especially for long walks - has insoles with cells filled with dampness absorbent material, and metal reinforcement strips join heel to toe

摘要

The shoe has an inner (8) and/or a permeable (12) insole sealing the top of the sole (1). Flexible metal reinforcement strips join the heel to the toe. The shoe sole has cells and hollow cavities (2) containing hygroscopic substances (5) absorbing humidity and which react with the air flow caused by the walking movement in the sole. The flexible, elastic sides or partitions (3) forming the cells contain air ducts conveying the air flow along the length of the sole during walking. A hollow cavity in the shoe's toe part contains an elastic, permeable filling (7). ADVANTAGE - The walking movement inside the shoe produces a light air flow without exchanging air with the outside so that the shoe is suitable for wet and or damp conditions.
