ABSTRACT:
A molded midsole encapsulating a series of parallel, spaced-apart tubes for shock absorption. The tubes are disposed perpendicular to the longitudinal axis of the sole. The tubes are constructed from a material somewhat more rigid than the surrounding molded material. The tubes may be arranged in the forefoot region, or in the heel region, or throughout the longitudinal span of the midsole. Transverse strips of tubing material may be used to space apart and join tubes to fabricate separate tube assemblies which are inserted directly in the midsole mold.
