Abstract
A shoe includes an upper with an open bottom portion which is a welt-like fold line unit. The fold line unit is defined by an outward turning part and an inward turning part which are sewn together through a sewing line unit. An interior strip unit is received inside the fold line unit and retained therein by the sewing line unit. An outsole connected to the upper, has a peripheral end with a top face extending proximate to the fold line unit. A insole connected to the upper has an outer edge which is separated and spaced apart from the welt-like fold line unit, whereby no part of the insole is included in the welt-like fold line unit and the fabrication thereof is simplified.
