  • Patent number: 6305103
    Abstract: The invention provides a footwear article that may be worn in a first mode which permits easy removal, or may be worn in a second mode that provides a secure fit. The article includes an elastic region and a locking component on at least one of its sides. When worn in the first mode, the elastic region is capable of stretching which may increase the wearer's comfort and facilitates the removing the article and putting on the article on at a later time. When worn in the second mode, a fastener, such as a shoelace, is engaged with the locking component prior to tying. The engagement between the locking component and the shoelace restricts the stretching of the elastic material, thus, maintaining a tight securement of the article on the foot. A variety of footwear articles are contemplated by the invention including shoes and boots.
