Claim 5

Shoe, comprising a relatively thin inner sole, an outer sole and an elastic intermediate sole disposed between said inner and outer soles, defining a tip, a heel, and regions accommodating the toes, the roots of the toes and the ball of the foot including a step point, said inner sole being substantially horizontal from the tip of the shoe to a location between the step point of the region accommodating the ball of the foot and the heel of the shoe, said intermediate sole having a relatively strong construction in vicinity of the region accommodating the ball of the foot as compared to the remainder of said intermediate sole and having an upwardly tapered section from the region accommodating the roots of the toes to the tip of the shoe, said intermediate sole having a multiplicity of holes formed therein in the region accommodating the toes for additionally reducing the hardness of said intermediate sole in the region accommodating the toes, said intermediate sole being in the form of an upper sole and a lower sole being cemented to each other, said upper sole being tapered down in the shape of a wedge from the heel to the tip of the shoe and having less elasticity than said lower sole.

Claim 6

Shoe according to claim 3, wherein said intermediate sole has other holes formed therein from the region accommodating the roots of the toes to the heel of the shoe, said other holes being less numerous and less concentrated than said first-mentioned holes in the region accommodating the toes.

Claim 7

Shoe according to claim 4, wherein said first-mentioned holes in the region accommodating the toes are relatively smaller and more numerous than said other holes from the region accommodating the roots of the toes to the heel of the shoe.

Claim 8

Shoe according to claim 4, wherein said holes in the heel of the shoe are exclusively disposed toward the middle of the heel.

Claim 9

Shoe according to claim 5, wherein said holes in the heel of the shoe are exclusively disposed toward the middle of the heel.

Claim 10

Shoe according to claim 3, wherein said holes are formed in said upper and lower soles and said holes in said upper sole are displaced relative to said holes in said lower sole.

Claim 11

Shoe according to claim 8, wherein said upper sole has less holes formed therein than said lower sole.

Claim 12

Shoe according to claim 1, wherein said holes are blind holes.

Claim 13

Shoe according to claim 10, wherein said blind holes are formed in the lower surface of said intermediate sole.

Claim 14

Shoe according to claim 1, wherein said inner sole is an exchangeble foot support.

Claim 15

Shoe according to claim 1, wherein said outer sole is formed of a relatively thin and tough flexible material.

Claim 16

Shoe according to claim 1, wherein said inner, intermediate and outer soles each have a substantially straight edge-formed along the side of a region accommodating the big toe.
