Abstract
A supporting device, particularly for sports shoes, which is constituted by a plurality of elements that are axially and elastically connected to each other. The elements are associated longitudinally with respect to the rear region of the shoe and have a curved shape at their mutual joining region. This device allows to control the articulation of the ankle, and particularly to control the longitudinal and lateral flexibility of the shoe.
Claims12
A supporting device in combination with a sports shoe, the supporting device comprising a plurality of elements axially and elastically connected to each other and longitudinally associated at a rear region of said shoe, said elements having mutually facing joining regions each having a curved shape and being mutually spaced apart such that a free rotation of one of said elements relative to another of said elements may occur upon a lateral oscillation applied to said shoe until an abutment between said mutually facing regions occurs for blocking said rotation, said elements being mutually axially and elastically connected by means of at least one adapted flexible bridge, and wherein each one of said elements comprises a body from which two first tabs protrude laterally, said tabs having tips and adapted first holes adjacent said tips that allow a coupling of said elements to said shoe.
A supporting device in combination with a sports shoe, the supporting device comprising a plurality of rigid elements axially and elastically connected to each other and longitudinally connected to said shoe at a rear region of said shoe, said plurality of elements comprising:
- at least one first element having a first central portion and a first pair of wings which extend in mutually opposite directions from said first central portion and which are connected to said shoe;
- and
- at least one second element having a second central portion and a second pair of wings which extend in mutually opposite directions from said second central portion and which are connected to said shoe;
- said supporting device further comprising:
- an elastic longitudinal bridge element interconnected between said first and second elements, said elastic longitudinal bridge element extending at said rear region of said shoe along a longitudinal median axis of said shoe, said elastic longitudinal bridge element being connected to each said central portion of said first and second elements, said elastic longitudinal bridge element being laterally elastically bendable upon a lateral oscillation applied to said shoe, and said elastic longitudinal bridge element being longitudinally elastically bendable upon a forward oscillation and a rearward oscillation applied to said shoe.
