The present invention relates to the upper U of an athletic shoe comprising a first openingout of which the foot sticks upwards during wearing and a second openingwhich is closed with a tongue. The two openingsare continuous with each other, and the upper U comprises a medial side stretchable partwhich covers a part of a medial side face of an arch of the foot, a lateral side stretchable partwhich covers a part of a lateral side face of a ball of a little toe (a fifth toe), a front partlocated forward of the two stretchable partsand a rear partlocated backward of the two stretchable parts. Each of the stretchable partsis provided so as to essentially cross one of side faces of the upper U from a top surface of a sole S to the second opening. Young's modulus along the lengthwise direction L of the foot of each of the stretchable partsis set smaller than that of the front partand the rear part

Athletic shoes having an upper whose fitting property is improved

A shoe sole includes a mid sole, and a reinforcing member reinforcing a portion of the mid sole, wherein the member () extends over an area from a mid foot part () to a rear foot part (), the member () including: a rod-shaped or strip-shaped main bar () provided along a line that is at the center of the foot; mid foot medial blades () and () and mid foot lateral blades (and) extending from the bar () in the part (); a plurality of rear foot blades (and) extending from the bar () in the part (), wherein the blades (to) are integral with the bar (), the blades (to) are attached to a lower surface of the mid sole, and at least a portion of each of the blades (and) is buried in the part ().

Shoe outsole and midsole

A midsole includes a thick plate-shaped or column-shaped cushioning portion. A plurality of grooves is formed on an outer peripheral surface of the cushioning portion. The respective grooves are helically formed around a substantially vertical line. The respective grooves are arranged substantially parallel with each other. A range &#x3b1; in which each of the grooves is formed is larger than a range of 15 degrees around the axial line and is smaller than a range of 180 degrees around the axial line.
