The modular insole system includes a base pad with a plurality forms releasably connected to the top surface thereof. The forms respectively correspond to orthotic support for the heel, arch, and ball portions of a foot. The forms are preferably releasably connected by hook and loop fastening material to the base pad and are made of foam. The forms are adjustable in any location on the top surface of the base pad to provide a custom configuration for a given user. The base pad and foam forms can be provided in different sizes, foam types, durometer hardness, and the like, and can be mixed and matched as needed to further customize the modular insole system for the given user. The forms have edges that complement each other so the insole can more closely simulate expensive custom insoles that are monolithic even when moved about on the base pad.

A shoe includes a sole, an upper portion disposed above the sole and surrounding a foot insertion part, and a buffer including a lower surface and accommodated within the foot insertion part. The lower surface of the buffer includes a projection part projecting toward a facing surface that faces the lower surface, a recess part adjacent to the projection part and recessed from the projection part toward the upper portion, and a circumferential edge projection part projecting, around the recess part, toward the facing surface side with respect to the projection part. When the buffer receives a predetermined first load, the circumferential edge projection part contacts the facing surface whereas the projection part has no contact with the facing surface, and when the buffer receives a predetermined second load, which is larger than the first load, the circumferential edge projection part and the projection part contact the facing surface.

A sole structure for an article of footwear includes a unitary sole with a first cushioning body having a first hardness and a second cushioning having a second hardness greater than the first hardness. Both the first and the second cushioning bodies are exposed at a periphery of the sole. The second cushioning body may have a wedge surface that interfaces with a lateral extremity of the first cushioning body and angles laterally outward toward a lateral side exterior surface of the sole from a lower extent to an upper extent of the wedge surface. The second cushioning body may underlie the first cushioning body in a portion of a forefoot region of the sole such that the first cushioning body establishes a foot-facing exterior surface and the second cushioning body establishes a ground-facing exterior surface of the sole where the first cushioning body overlies the second cushioning body.

An article of footwear includes an outsole, an upper secured to the outsole and defining a foot-receiving cavity and an ankle opening, and a unitary, full-length midsole having a forefoot region, a midfoot region, and a heel region, and configured to be removably inserted into the foot-receiving cavity through the ankle opening. The midsole includes a first cushioning body having a first hardness and a second cushioning body having a second hardness greater than the first hardness. The midsole has a lateral side, a medial side, a forwardmost extent disposed in the forefoot region, and a rearmost extent disposed in the heel region. The second cushioning body includes a lateral segment that extends through the lateral side in the forefoot region, and a portion of the lateral segment of the second cushioning body is closer to the forwardmost extent than to the midfoot region.

An article of footwear includes an upper and a sole structure with a sole member. The sole member can be manufactured using a system that modifies the forefoot cushioning of the sole member over a series of footwear purchases. The modifications can be configured to correspond to a customer's evaluation of the forefoot cushioning previously purchased. The sole member can include a set of apertures or incisions that are formed along various surfaces of the sole member to adjust the cushioning characteristics of the sole member.
