Abstract: A universal open-backed footwear strap having a strap having an adjustable fastener and a first connector mechanism. A second connector mechanism disposed on a sole of an open-backed shoe, wherein the second connector mechanism is selectively engageable with the first connector mechanism. The first connector mechanism and second connector mechanism create a strong enough attachment between the strap and the shoe such that they will not separate during use. The adjustable fastener can then be used to tighten the strap around a top of a user's foot to secure the shoe, eliminating the typical instability of open-backed shoes to allow the user to move more quickly and confidently, and to dance. The strap can be made available in a variety of materials and colors so as to match any shoe. Different length straps will allow for use with different shoe types and foot sizes.
