Claims20
A spike for an article of footwear, the spike comprising:
- a first portion configured to be attached to the article of footwear, the first portion including (i) a base extending from a first end to a second end along an axial direction, and (ii) a first flange extending radially outward from the first end of the base, wherein the first flange includes a first mating surface formed on an opposite side of the first flange than the base;
- and
- a second portion including (i) a second flange including a second mating surface attached to the first mating surface of the first portion and an outer surface opposite the second mating surface, and (ii) a single annular ridge continuously projecting from a periphery of the outer surface away from the first portion, wherein the second portion forms a ground-engaging surface of the spike.
A spike for an article of footwear, the spike comprising:
- a first portion configured to be attached to the article of footwear and being formed from a first polymeric material having a first hardness, the first portion including (i) a base extending from a first end to a second end along an axial direction, and (ii) a first flange extending radially outward from the first end of the base, wherein the first flange includes a first mating surface formed on an opposite side of the first flange than the base, and wherein a radially outermost portion of the first flange is exposed;
- and
- a second portion including (i) a second flange including a second mating surface attached to the first mating surface of the first portion and an outer surface opposite the second mating surface, and (ii) an annular ridge projecting from and outlining a periphery of the outer surface away from the first portion, wherein the periphery continuously extends along the outer surface, wherein the second flange includes an exposed radially outermost portion, and wherein the second portion forms a ground-engaging surface of the spike and is formed from a second polymeric material having a second hardness that is different from the first hardness.
A spike for an article of footwear, the spike comprising:
- a first portion configured to be attached to the article of footwear and being formed from a nylon material having a first hardness, the first portion including (i) a base extending from a first end to a second end along an axial direction, and (ii) a first flange extending radially outward from the first end of the base, wherein the first flange includes a first mating surface formed on an opposite side of the first flange than the base;
- and
- a second portion including (i) a second flange including a second mating surface attached to the first mating surface of the first portion and an outer surface opposite the second mating surface, (ii) an annular ridge projecting from a periphery of the outer surface away from the first portion, and (iii) a central projection being centered on the second flange and projecting away from the first portion, wherein the annular ridge continuously encircles the central projection along the periphery, wherein a cross-sectional profile of the annular ridge taken along a plane parallel to a longitudinal axis of the first portion tapers to a point, and wherein the central projection forms a ground-engaging surface of the spike.
