• a plurality of bars extending downward from the lower surface of said base member and transverse to the lengthwise direction thereof, said bars being spaced from one another in the lengthwise direction of said base member, and being located along substantially the entire length thereof, said bars in said heel and forefoot sections being wider than the bars in said arch and toe sections, the width of the bars in said heel and forefoot sections varying in width, the widest of said bars in said heel section being the rearmost bar in said heel section and the width of the remaining bars in said heel section progressively decreasing in width therefrom, the widest of said bars in said forefoot section being located adjacent the central area in the lengthwise direction of said forefoot section and the width of the remaining bars in said forefoot section progressively decreasing in width to either side of the widest bar in said forefoot section;
• a plurality of supplemental bars extending downwardly from the bars in said toe and arch sections, each of said supplemental bars having a width substantially equal to the bar from which it extends, the length of the supplemental bars in said toe section increasing in length from the forwardmost of said supplemental bars to the rearmost supplemental bar in said toe section, the widest of said supplemental bars in said arch section being adjacent the forefoot section and the remaining supplemental bars in said arch section progressively decreasing in length therefrom toward the central lengthwise area of said arch section and thereafter increasing in length toward the heel section;
• a plurality of intermediate bars extending from the bars of said forefoot and heel sections, each of said intermediate bars having a width substantially equal to the width of the bar from which it extends, the length of said intermediate bars in said forefoot section being the widest at approximately the central lengthwise area of said forefoot section and progressively decreasing in length on either side thereof, the length of the intermediate bars in said heel section being greatest at the rearmost of said intermediate bars and progressively decreasing therefrom.

An athletic shoe comprising;

• a shoe upper;
• a sole secured to said shoe upper;
• said sole including an outer sole having a base member formed of resilient material, said base member having a heel section, an arch section, a forefoot section, a toe section and a lower surface for facing the ground;
• a plurality of bars extending downward from the lower surface of said base member and transverse to the lengthwise direction thereof, said bars being spaced from one another in the lengthwise direction of said base member, said bars having widths in he lengthwise direction of the outer sole which are varied in proportion to the load exerted at particular locations along the lengthwise direction of said outer sole during running, whereby said bars are wider at areas of greater load and are narrower at areas of less load;
• and
• an intermediate bar extending downward from a plurality of said bars in each of said forefoot and heel section, the length of said intermediate bars in the transverse direction of the outer sole varying in proportion to the load exerted at particular locations along the lengthwise direction of said outer sole during running, whereby said intermediate bars are longer at areas of greater load and are shorter at areas of less load.
