Adjustable strap shoes are shoes that are secured to the foot using some type of fastening device that can be customized to the wearer's foot. Types of adjustable straps include hook and loop fasteners or buckles.
A zipper, sometimes called a 'slide fastener' is a device consisting of two toothed tracks or spiral metal or plastic coils, each bordering one of two edges to be joined, and a piece that either interlocks or separates them when pulled.
