-
FIG. 1 illustrates aconventional shoe sole 1 attached to an upper of a footwear article. Theshoe sole 1 includes anoutsole 10 formed with arecess 11, and anelastic body 12 received in therecess 11. Theelastic body 12 is formed with a plurality of vertically extending through-holes 13, each of which is filled with afiller 14 so as to provide a shock absorbing effect. However, since the structure thus formed for theelastic body 12 has a relatively poor compressibility in a compression direction (Y) toward the ground, the shock absorbing effect provided by theconventional shoe sole 1 is relatively poor when a downward force (F) is applied to theshoe sole 1. - The object of the present invention is to provide a shoe sole that can overcome the aforesaid drawback of the prior art.

FIG. 10 is a schematic view of the sixth preferred embodiment according to this invention. -
FIGS. 2 to 4 illustrate the first preferred embodiment of a shoe sole of a footwear article according to this invention. - The shoe sole includes: a
sole unit 2 defining at least onerecess 20; at least oneelastic body 3 received in therecess 20 and having a cellular structure that defines at least two levels ofcells 30, the two levels of thecells 30 being disposed one above the other, each of thecells 30 defining a cell space therein; and afiller material 34 that fills the cell space of each of thecells 30. - In this embodiment, the
sole unit 2 includes anoutsole 21 that defines therecess 20 disposed at a heel portion of the shoe sole, and atread member 22 attached to theoutsole 21 and covering a bottom side of therecess 20. The cellular structure of theelastic body 3 has a surroundingwall 31 that defines aninner space 310 and that is disposed between and that is attached to theoutsole 21 and thetread member 22, and a plurality of interconnectedwebs 32 that are disposed in theinner space 310 and that are connected to the surroundingwall 31 so as to define thecells 30. Note that thewebs 32 and the surroundingwall 31 are formed integrally into one single piece in this embodiment. - Preferably, the
filler material 34 is selected from the group consisting of gel, silicone, polyurethane resin, and soft rubber. - The surrounding
wall 31 has twoopen ends 35 that are opposite to each other in a horizontal direction (Z). Each of theopen ends 35 of the surroundingwall 31 defines anopening 350. Each of thewebs 32 extends between theopen ends 35 of the surroundingwall 31. Each of thecells 30 extends in the horizontal direction (Z). The shoe sole further includes anelastic film 33 that is attached to one of theopen ends 35 of the surroundingwall 31 so as to cover the opening 350 of said one of theopen ends 35 of the surroundingwall 31. - In this embodiment, the surrounding
wall 31 has a curvedupper wall portion 311 and a curvedlower wall portion 312 connected end-to-end to theupper wall portion 311. Thewebs 32 are grouped into substantially parallelfirst webs 32 and substantially parallelsecond webs 32 that extend in a direction opposite to that of thefirst webs 32 and that intersect thefirst webs 32 to form thecells 30. Preferably, each of thewebs 32 is inclined relative to the upper andlower wall portions wall 31 such that a top vertex angle θ of each of thecells 30 is greater than 90 degrees. -
FIG. 5 illustrates the first preferred embodiment disposed in a compressed state. By virtue of the cellular structure, the compressibility of theelastic body 3 in the compression direction (Y) toward the ground is enhanced as compared to the aforesaid conventional shoe sole, and theelastic body 3 can be easily deformed by a downward force (F), thereby enhancing the shock absorbing effect. At the compressed state, the top vertex angle θ is enlarged as a result of the downward force (F). -
FIG. 6 illustrates the second preferred embodiment of the shoe sole according to this invention. The shoe sole differs from the previous embodiment in the cellular structure of theelastic body 3. The cellular structure of theelastic body 3 of this embodiment has four levels of thecells 30. Each level includes different sizes of thecells 30. The different sizes of thecells 30 of the four levels are arranged in a staggered manner. -
