A spike is operable to be removably coupled to an article of footwear. The spike includes a first portion that is substantially rigid. The spike also includes a second portion that is resilient.

Spike for footwear having rigid portion and resilient portion

An article of footwear includes an upper, an outsole, and a midsole disposed between the upper and the outsole. The outsole is attached to the upper and has a ground-engaging surface. The midsole has a series of walls that define a series of channels extending substantially perpendicular to a longitudinal axis of the midsole and along an entire length of the midsole. The series of channels are isolated from one another and each channel receives a quantity of particulate matter therein.

Particulate foam with partial restriction

An article of footwear includes an upper, a midsole attached to the upper, and an outsole. The midsole has a footbed and a bottom surface disposed on an opposite side of the midsole than the footbed. The outsole has a ground-engaging surface, an inner surface disposed on an opposite side of the outsole than the ground-engaging surface, and a wall extending from the ground-engaging surface and surrounding the outsole. The article of footwear also includes a casing containing particulate matter and having a length that is greater than a length of the outsole. The casing includes a first fold at a predetermined location along its length. The casing is received within a cavity bounded by the wall of the outsole and between the bottom surface and the inner surface.

Particulate foam with flexible casing

An article of footwear having a removable outsole, midsole, and upper is provided. A portion of the upper may have a perimeter lip that may be coupled to a perimeter channel in an upper surface or side of the outsole. The midsole may be securely placed into the upper to further secure the upper to the outsole. The fit of the outsole, upper, and midsole generates a securely assembled article of footwear ready for user wear. In aspects, the removable outsole, midsole, and upper may be changed to customize the article footwear for the user.

Footwear with removable midsole and outsole

An apparatus for manufacturing footwear, the apparatus including a jig and a cutting die. The jig including a base member and a plurality of pins, the jig having an outline conforming to an entire outline of a conventional midsole of an article of footwear and having an upwardly facing top surface configured to engage a foam midsole member, and the plurality of pins positioned about a periphery of the base member and projecting upwardly. The cutting die having a plurality of blades configured to form sipes in the lower surface of the foam midsole member, the cutting die being movable toward the top surface of the base member to bring the blades into contact with the foam midsole member disposed between the cutting die and the base member.

Cutting assembly for manufacturing footwear having sipes

An article of footwear is disclosed that includes an upper and a sole structure secured to the upper. The sole structure incorporates a support element that includes a fluid-filled chamber. The chamber may be bonded to other portions of the sole to secure the chamber within the sole. A surface of the chamber may also be angled to form a corresponding bevel in a lower surface of the sole structure, potentially in a rear-lateral area of the sole structure. A plate may also extend under a portion of the chamber.
