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). The present description also relates to a method which can be realized by this sole, as well as to a footwear comprising this sole.

A method for modifying the configuration of a leaning surface (3) of a sole (1) for footwear, wherein the leaning surface (3) is configured to face, in use, towards a walking surface, wherein the method comprises the steps of:

providing a first layer (2) of a footwear sole (1), defining said leaning surface (3),
providing a second layer (4) of a footwear sole (1) comprising a plurality of chambers (5),
coupling said first layer (2) and said second layer (4),
providing an actuation system (6) including a fluid source (7) comprising a feeding fluid and connected to said plurality of chambers (5),
controlling the feeding fluid supply from the fluid source (7) to said plurality of chambers (5), so as to determine a variation in the volume of said chambers (5) between a rest condition and an active condition,
wherein in said rest condition the chambers (5) have a first volume (v1) and determine a first configuration of the first layer (2),
and wherein in said active condition the chambers (5) have a second volume (v2), greater than said first volume (v1), and 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).
