FOOTWEAR HAVING GRANULATED MATERIAL FOR APPLYING PRESSING STIMULATION TO SOLE AND CIRCUMFERENTIAL SIDE OF FOOT

PROBLEM TO BE SOLVED: To provide footwear for providing massage and stimulation to the entire soles of the feet by repeating a non-pressure state and a pressurized state. SOLUTION: The footwear provides appropriate stimulation as if walking on the ground or sands with bare feet. Granulated material 3 sealed in a bag 2 formed of elastic material is inserted into an outsole 1 having a three-dimensional structure and formed of synthetic resin, cloth, nonwoven fabric or the like. The outsole 1 is sewn, adhered, or welded with the bottom and a top plate 4, and an instep band is also provided by sewing, adhering, or welding. The non-pressure state and the pressurized state are repeated on the top plate of the outsole having a space for storing the granulated material so that the granulated material inside is forcibly moved. In the pressurized state, the granulated material rises not only horizontally but also vertically, specially in a direction toward the arch of the foot so as to uniformly stimulate the entire sole of the foot. In the non-pressure state, a raised part is pressed downward and become flat by contractibility of the top plate. COPYRIGHT: (C)2006,JPO&NCIPI
