Abstract: An insole board for a high-heel shoe, said insole board includes a heel supporting area having a concave heel cup adapted to underlie a heel of the wearer, a medial arch support area adapted to underlie the arch of the wearer's foot and extending toeward of but short of the ball of the wearer's foot, and a forefoot area adapted to underlie the ball of the foot and forefoot of the wearer. The medial arch support area has a raised contour for supporting a portion of a sole of the wearer's foot underlying the wearer's arch, and the forefoot support area includes a hollow having a resiliently deformable material therein.
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.
