    a midsole, the midsole having (i) a toe end, (ii) a heel end, (iii) an inner side, and (iv) an outer side, wherein a perimeter of the midsole is stitched to the upper thereby forming a bottom to the interior portion that is bounded by a first seam;

    a heel outsole patch stitched onto a heel portion of a first face of the midsole;

    a toe outsole patch stitched onto a toe portion of the first face of the midsole; and

    an insole that is affixed by glue to the bottom of the interior portion,wherein there is a spacing between (i) the heel outsole patch stitched onto the heel portion of the first face of the midsole and (ii) the toe outsole patch stitched onto the toe portion of the first face of the midsole, the spacing extending from the inner side to the outer side and occupying a position intermediate the toe end and the heel end thereby permitting the entire shoe to fold about an axis in the spacing running between the inner side and the outer side, andwherein the shoe is configured to fold between (i) an extended state wherein the heel outsole patch and the toe outsole patch are coplanar and (ii) a folded state in which the shoe is bent about the axis such that a portion of the upper comprising the toe cavity is tucked into the heel cavity, and wherein the insole is not stitched to the upper.
