Abstract: A sole for footwear and footwear including the sole are disclosed. The sole includes a first layer having a plurality of orifices passing through and configured to be connected to an upper of a footwear article and to form an inner environment of the footwear, a second layer coupled to the first layer, having a plurality of chambers and one or more channels or passages fluidly connecting the orifices and chambers. The sole also includes a pressurization device in fluid communication with the channels or passages and is configured to increase the air pressure in the plurality of chambers and regulating valves in fluid communication with the channels or passages to regulate a pressure in the plurality of chambers.

Abstract: The present description relates to a footwear sole (1) comprising a first layer (2) having a leaning surface (3) and a second layer (4), coupled to said first layer (2), associated with a plurality of seats (5). The sole (1) moreover comprises a plurality of actuated members (6) each of which mounted in a respective seat (5) and movable or shift-able between a first position, or retracted position, and a second position, or extended position, wherein in the respective first position they are apt to determine a first configuration of the first layer (2) and in the second position they are apt to determine a second configuration of the first layer (2) wherein the leaning surface (3) has or forms a plurality of bumps or protrusions with respect to the first configuration. The sole (1) further comprises an actuation member (7) configured to move the actuated members (6) between the first position and the second position, and vice versa.

Abstract: Footwear sole (1) comprising a first layer (2) defining a leaning surface (3) configured to face, in use, a walking surface and a second layer (4) comprising in turn a plurality of chambers (5) and coupled to said first layer (2). Moreover, the sole (1) comprises an actuation system (6) including a fluid source (7) comprising a feeding fluid and connected to said plurality of chambers (5). The actuation system (6) is configured to control the supply of a fluid to said plurality of chambers (5) between a rest condition and an active condition, and vice versa. In particular, in said rest condition the chambers (5) have a first volume (v1) and are apt to determine a first configuration of the first layer (2), while in said active condition the chambers (5) have a second volume (v2), greater than said first volume (v1), and are apt to determine a second configuration of the first layer (2) wherein the leaning surface (3) has or forms a plurality of bumps at each of said plurality of chambers (5).

Abstract: A back protector is described, having a body with energy-absorbing function extending along a longitudinal direction (L) and having a portion able to provide the body with energy-absorbing function with a freedom of movement according to at least six degrees of freedom; and/or allow return into an original position following cessation of all the following stresses: stretching along the longitudinal direction, a compression, in the opposite direction to the stretching, along the longitudinal direction, a torsion in both directions of rotation about an axis passing through the body with energy-absorbing function, the axis being parallel to the longitudinal direction, a bending towards right-hand and left-hand sides of the body with energy-absorbing function about an axis orthogonal to a plane supporting the body with energy-absorbing function and orthogonal to the longitudinal direction (L), and/or a combination of the stresses.
