Abstract
Sandals with biomechanical foot support, robust usability and cost-effectiveness are disclosed. The footwear may comprise a biomechanical sole and a Y-shaped rubber strap anchored to the sole. The sole has a top surface including a raised contour on the medial side of the sandal, and a low profile heel cup. The raised contour on the medial side and the heel cup match the natural anatomic shape of the foot, and thus provides a biomechanical foot support. The bottom surface of the sole may be a roughed surface to provide necessary traction and friction when a wearer/user walks. The bottom surface further comprises a plurality of grooves to allow water to be expelled and increase traction.
Claims18
A footwear product comprising:
- a sole having a top surface and a bottom surface, the top surface comprising a foot supporting surface including a forefoot supporting contour, a raised medial contour and a concave heel cup, the bottom surface incorporating an oval-shaped cavity under the medial contour, the oval-shaped cavity having a major axis aligned in a longitudinal direction of the sole and a minor axis aligned in a traverse direction of the sole, wherein the oval-shaped cavity permits the sole to deform or collapse from the top when a user walks;
- wherein the sole has a maximum thickness at a medial edge of the medial contour, and wherein the oval-shaped cavity has a depth at its lowest point of between ¼ and ⅓ of the maximum thickness of the sole;
- a strap anchored to the sole via at least one anchor point.
A footwear product comprising:
- a sole having a top surface and a bottom surface the top surface comprising a foot supporting surface including a forefoot supporting contour, a raised medial contour and a concave heel cup, the bottom surface incorporating an oval-shaped cavity under the medial contour, wherein the oval-shaped cavity has a depth at its lowest point of between ¼ and ⅓ a maximum thickness of the medial contour, and a major axis aligned in a longitudinal direction of the sole and a minor axis aligned in a traverse direction of the sole, wherein the oval-shaped cavity permits the sole to deform or collapse from the top when a user walks;
- and
- a Y-shaped strap comprising a first strap arm and a second strap arm anchored to the sole via a front anchor point, a first rear anchor point and a second rear anchor point, the rear anchor points being offset relative to a heel end of the sole.
A method for making a footwear product, comprising:
- providing a unisole as a biomechanical foot support, the unisole having a top foot supporting surface and a bottom surface, the top foot supporting surface comprising a forefoot supporting contour, a raised medial contour and a concave heel cup, the bottom surface incorporating a cavity under the medial contour having a major axis aligned in a longitudinal direction of the sole and a minor axis aligned in a traverse direction of the sole, wherein the sole has a maximum thickness at a medial edge of the medial contour, and wherein the cavity has a depth at its lowest point of between ¼ and ⅓ of the maximum thickness of the sole;
- wherein the cavity permits the sole to collapse from the top when a user walks;
- and attaching a strap to the unisole via at least one anchor point on the sole.
