Patent number: 7464491Abstract: A pair of casual shoes such as flip-flops are packaged for sale so as to have the general appearance of an essentially spherical ball. Each shoe has a flexible sole portion and an upper portion connected to at least part of the periphery of the sole portion by stitching, which extends around the entire sole portion periphery. The sole portion of each shoe is flexed generally into a U-shape and also is flexed transversely to the length thereof, and then the two U-shapes are interfitted with the toe and heel regions of one shoe fitting against the instep region of the other shoe. An elongate cord is laced between the stitching around the peripheries of the two sole portions so as to hold the two shoes together in the ball shape but removal of the cord release the two shoes for separation and opening out into a pair of flip-flops.Type: GrantFiled: September 21, 2006Date of Patent: December 16, 2008Inventor: Yoko Nakayama
