A sole structure for an athletic shoe includes a heel region and a forefoot region, a midsole of a soft elastic material including a midsole heel portion at the heel region, and an outsole of a harder material including an outsole heel portion at the heel region and an outsole forefoot portion that extends from the outsole heel portion to the forefoot region. The midsole heel portion has wavy corrugations on a lower surface thereof and a smooth plane on an upper surface thereof. The outsole heel portion includes a corrugated wavy plate with corrugations through its thickness, which are in phase with the wavy corrugations on the lower surface of the midsole heel portion.

Sole design and structure for athletic shoe

An athletic shoe sole structure includes a midsole body that extends from a heel region to a forefoot region of a shoe, and an outsole body that is disposed under the midsole body, extends from the heel region to the forefoot region of the shoe, and is formed of a harder material than the midsole body. A heel portion of the outsole body includes a corrugation. The sole structure further includes a lower midsole disposed under the heel portion of the outsole body, an outsole heel portion attached at a lower surface of the lower midsole, and cleats provided at a lower surface of the outsole body. The sole structure having only two layers with the outsole and the midsole decreases the weight of the shoe, simplifies a manufacturing process, and reduces a manufacturing cost.

A shoe sole structure includes an outsole that extends from a heel region to a forefoot region of a shoe, and a midsole that is disposed above the outsole and extends from the heel region to a midfoot region of the shoe. A heel portion of the outsole includes a corrugated portion. A heel portion of the midsole includes a corrugated portion, which corresponds in phase to the corrugated portion of the outsole. Cleats are provided at a bottom surface of the outsole. The corrugated portion on the outsole provides running stability. The sole structure having only two layers with the outsole and the midsole decreases the weight of the shoe, simplifies a manufacturing process, and reduces a manufacturing cost.

A dreging helical cutter suited for use, for example, with a dredger is equipped according to the present invention with scoop-in plates. Earth and sand is transported by helical vanes to a send-out end portion of the helical cutter. The scoop-in plates transport the earth and sand to an opening of an earth/sand suction tube. The opening of the suction tube is provided in a portion of the helical cutter for receiving a rotary shaft. All of the earth and sand excavated by the helical cutter can therefore be sucked into the suction tube and the efficiency of the dredging operation can be greatly increased by a simple structure.
