Abstract
A sole portion for an item of footwear having a plurality of cleat systems, cleats, or plate structures that dissipate force by deflecting, deforming, displacing or otherwise shifting under selected force, or by facilitating cleat movement around a radial line during ground engagement.
Claims12
A sole portion of a shoe, comprising:
- a plurality of cleat systems disposed on a sole plate comprising an upper plate and a lower plate that are interconnected by an elastomeric structure, each cleat system comprising a cleat disposed on the lower plate, each cleat having a head portion for engaging a ground surface and a base portion that is disposed on the lower plate, the lower and upper plates being arranged in non-overlapping, generally parallel planes so that the upper and lower plates are configured to laterally and axially displace relative to one another along an X and/or Y axis;
- and
- wherein under load the elastomeric structure shifts to a transverse orientation and the upper plate, along with an associated foot compartment, shifts axially and laterally over the lower plate in the direction of an applied force.

- wherein under load the elastomeric structure shifts to a transverse orientation and the upper plate, along with an associated foot compartment, shifts axially and laterally over the lower plate in the direction of an applied force;
- and
- wherein the lower and upper plates have differential firmness so that one plate elastically deforms relative to another under compressive loads, opposing surfaces of the plates being separated by one or more spacers disposed on one of the opposing surfaces of a plate that engage an elastically deformable surface of the opposing plate to deform that surface under load.
