Abstract
Stretchable shoes capable of being fixed without causing any stretch of the shoes once adjustment of a size thereof depending on a wearer is completed. Velcro-type hook and loop fasteners are arranged on a heel, so that a size of the shoes may be kept fixed once adjustment of the size is carried out, because engagement between the fasteners exhibits rigidity to a degree sufficient to substantially prevent release of the engagement. Also, the stretchable shoes permit adjustment of a size of the shoes to be readily accomplished by merely loosening a single countersunk screw kept tightened.
