Abstract:
1. Cushioning element for footwear, having a deformable filling and an envelope that encloses the deformable filling, wherein the envelope is arranged for forming at least one flow channel, wherein, in use, at least part of the deformable filling flows into the at least one flow channel as a result of increased pressure of the deformable filling caused by a mechanical load, wherein the deformable filling contains solid bodies and further contains a lubricating fluid for mutually lubricating the solid bodies, wherein the at least one flow channel is dimensioned for hindering entrance of the solid bodies into the at least one flow channel during cushioning, wherein the envelope has an elastically variable volume, and wherein the envelope is arranged for forming the at least one flow channel by developing, substantially reversibly, a bulge in at least one deformable portion as a result of increased pressure of the deformable filling exerted on the at least one deformable portion, caused by the mechanical load, and wherein the at least one flow channel is dimensioned for inhibiting entrance of the solid bodies into the at least one flow channel during cushioning.
