A sole structure for an article of footwear may have a midsole system that includes a sole plate having a forefoot region and a midfoot region. The sole plate may have a foot-facing surface and a ground-facing surface opposite to the foot-facing surface. The sole plate may define a through hole extending from the foot-facing surface to the ground-facing surface in the forefoot region. The through hole may be closer to a medial edge of the sole plate than to a lateral edge of the sole plate. The sole plate may have ridges extending longitudinally in the midfoot region and in the forefoot region. The ridges may have crests at least some of which may extend non-parallel with one another in a longitudinal direction of the sole plate.

This document discloses algae-derived flexible foams, whether open-cell or closed-cell, with inherent antimicrobial and flame resistant properties, wherein a process of manufacturing includes the steps of: harvesting algae-biomass; sufficiently drying the algae biomass; blending the dried algae biomass with a carrier resin and various foaming ingredients; adding an algal-derived antimicrobial compound selected from various natural sulfated polysaccharides present in brown algae, red algae, and/or certain seaweeds (marine microalgae); and adding a sufficient quantity of dried algae biomass to the formulation to adequately create a fire resistant flexible foam material.

A sole structure for an article of footwear includes a first midsole body and a second midsole body. The first midsole body defines a ground-facing surface and a foot-facing surface opposite the ground-facing surface and includes a first midsole material, which has a first hardness. The second midsole body extends through the first midsole body. As such, the second midsole body extends beyond the ground-facing surface of the first midsole body. The second midsole body includes a second midsole material, which has a second hardness, and the first hardness is greater than the second hardness.

A component for a shoe, intended to be interposed between a foot and the ground, is delimited by an upper surface which, in use, is turned towards the foot. The upper surface comprises a load-bearing region in which at least one recess is made, the recess being configured to receive at least one metatarsal head of the foot, so that in the load-bearing region a plurality of metatarsal support levels is defined, the metatarsal support levels being placed at different heights from one another and being intended to support the metatarsal heads of the foot. The plurality of metatarsal support levels comprises, in the more simplified embodiment, two different metatarsal support levels. In a more complex embodiment, three different metatarsal support levels are provided. In a more complete embodiment, five different metatarsal support levels are provided.

A sole structure for a shoe that can secure cushioning properties and obtain a ground surface information is disclosed. The sole structure includes a first midsole having a plurality of first protrusions on a foot-sole-contact side, an outsole having a plurality of second protrusions on a ground surface side, and a second midsole disposed at a part of a region between the first midsole and the outsole and having a lower compressive rigidity than the first midsole. At least a part of the plurality of first protrusions of the first midsole is located at a position corresponding vertically to at least a part of the plurality of second protrusions of the outsole.
