Disclosed herein is a fastening structure which enables objects to be easily removeably coupled, and enables a smooth slideable coupling and decoupling. The fastening structure includes a male and female component. The male component is cross shaped with a wing member and cross bar member. The female component has a complementary structure with an elongate slot and cross groove, such that the male component is slideably received and mated.

A shoe comprises a sole having an upper surface with an outer edge and a lower surface. There is a top member having a distal front end portion, a proximal heel end portion, a lateral side and a medial side, the top member and sole defining a space therebetween to receive a foot. The top member further has a foot opening, a lower connective edge, a fold back portion, and a fixed portion. A single fastening means is provided in the form of one continuous zipper fastener in the top member. The top member has multiple expandable vent areas formed from a stretchable material in the top member allowing the top member to adjust in size to accommodate foot braces of many sizes and shapes.

An article of footwear and method of manufacturing includes a midsole, an upper, secured with respect to the midsole, forming an opening to admit a foot of a wearer, the opening being adjustable between a first segment of the upper and a second segment of the upper to secure the article of footwear to the foot of the wearer, and a slidable securing device. The slidable securing device is coupled between the first segment and the second segment of the upper, configured to slide along a length of track and secure the first and second segments together. A motorized lacing system engages with a lace to increase and decrease tension on the lace. The lace is secured to the slidable securing device, and when tension is placed on the lace, the lace causes the slidable securing device to slide along the track and secure the first and second segments together.
