Abstract
Abstract The present invention relates to a spiked shoe comprising a sole provided with a plural number of spikes on the lower surface thereof, and an upper mounted on said sole, wherein the effective part of each spike comprises a parallel element having uniform cross section in form and area through the length thereof, the bottom face of said parallel element being of a shape cut by a plane vertical to the axis of the spike.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
181 words
A spiked shoe comprising a sole and an upper mounted on the sole, the sole having a lower surface, a plurality of spikes extending from the lower surface of the sole, each spike having a longitudinal axis and an effective part which extends between the lower surface of the sole and the lower end of the spike, the effective part of each spike comprising an upper part extending axially Downwardly from the lower surface of the sole and a lower part extending axially downwardly from the upper part and formed integrally therewith, each of the upper and lower parts extending parallel to the longitudinal axis of the spike and having a uniform cross section throughout the length thereof, the cross section of the upper part being larger than the cross section of the lower part, the lower end of each lower part having a planar surface crossing the axis of the spike and the lower end of each upper part having a resistance face extending outwardly beyond the lower part for checking unnecessarily deep penetration of the spike into the track.
Claim 2
Dependent Claim
181 words
A spiked shoe comprising a sole and an upper mounted on the sole, the sole having a lower surface, a plurality of spikes extending from the lower surface of the sole, each spike having a longitudinal axis and an effective part which extends between the lower surface of the sole and the lower end of the spike, the effective part of each spike comprising an upper part extending axially Downwardly from the lower surface of the sole and a lower part extending axially downwardly from the upper part and formed integrally therewith, each of the upper and lower parts extending parallel to the longitudinal axis of the spike and having a uniform cross section throughout the length thereof, the cross section of the upper part being larger than the cross section of the lower part, the lower end of each lower part having a planar surface crossing the axis of the spike and the lower end of each upper part having a resistance face extending outwardly beyond the lower part for checking unnecessarily deep penetration of the spike into the track.
Claim 3
Dependent Claim
23 words
The shoe of claim 1 in which the planar surface of each lower part extends perpendicularly to the longitudinal axis of the spike.
Claim 4
Dependent Claim
22 words
The shoe of claim 1 in which the resistance face of each spike extends perpendicularly to the longitudinal axis of the spike.
Claim 5
Dependent Claim
31 words
The shoe of claim 1 in which the planar surface of each lower part and the resistance face of each upper part extend perpendicularly to the longitudinal axis of the spike.
Claim 6
Dependent Claim
19 words
The shoe of claim 1 in which the upper and lower parts of each spike having circular cross sections.
Claim 7
Dependent Claim
217 words
A spiked shoe comprising a sole and an upper mounted on the sole, the sole having a lower surface, a plurality of spikes extending from the lower surface of the sole, each spike having a longitudinal axis and an effective part which extends between the lower surface of the sole and the lower end of the spike, the effective part of each spike comprising an upper part extending axially downwardly from the lower surface of the sole and a lower part extending axially downwardly from the upper part and formed integrally therewith, the lower part extending parallel to the longitudinal axis of the spike and having a uniform cross section throughout the length thereof, the lower end of each lower part having a planar surface crossing the axis of the spike, the upper part including a first portion extending axially downwardly from the lower surface of the sole and extending parallel to the longitudinal axis of the spike and having a uniform cross section through the length thereof and an expanded portion between said first portion and the lower part of the spike extending outwardly beyond the first portion, the lower end of the expanded portion having a resistance face extending outwardly beyond the lower part for checking unnecessarily deep penetration of the spike into the track.
Claim 8
Dependent Claim
217 words
A spiked shoe comprising a sole and an upper mounted on the sole, the sole having a lower surface, a plurality of spikes extending from the lower surface of the sole, each spike having a longitudinal axis and an effective part which extends between the lower surface of the sole and the lower end of the spike, the effective part of each spike comprising an upper part extending axially downwardly from the lower surface of the sole and a lower part extending axially downwardly from the upper part and formed integrally therewith, the lower part extending parallel to the longitudinal axis of the spike and having a uniform cross section throughout the length thereof, the lower end of each lower part having a planar surface crossing the axis of the spike, the upper part including a first portion extending axially downwardly from the lower surface of the sole and extending parallel to the longitudinal axis of the spike and having a uniform cross section through the length thereof and an expanded portion between said first portion and the lower part of the spike extending outwardly beyond the first portion, the lower end of the expanded portion having a resistance face extending outwardly beyond the lower part for checking unnecessarily deep penetration of the spike into the track.
