Patent ID: 11805848

Abstract:
a foldable shoe, comprising: a sole extending between a toe end and heel end, the sole comprising a toeroom region proximate the toe end and a heel region proximate the heel end and a midfoot region defined between the toeroom region and heel region, the toeroom region comprising a strap spanning the width of the shoe in a toe-lever region of the toeroom region, the heel region comprising at least one strap retainment recess, configured to alternately: receive the strap and retain the strap against slipping off of the sole and mitigate stress concentrations against breakage under the tensile strength of the strap and bending strength of the sole, when the shoe is folded; and define the compression strength of the sole in the heel region, such that the shoe is configured to alternately: receive a foot of a user with a ball of the user's foot retained in the midfoot region with a stretchable upper portion of the shoe that is independent of the strap; and fold into a retainment orientation, with the heel region retained in a parallel offset orientation to the toeroom region with the strap, with the upper portion contained between the toeroom region of the sole and the heel region of the sole, with the strap traversing under the sole in the heel region and retained in the strap retainment recess.
