Abstract

Strap type securing systems, e.g., for footwear or other foot-receiving devices, include a strap support with a slot located between its opposite ends. A slot reinforcement may be provided, e.g., adjacent at least some portions of the slot edge, corners, and/or ends, to prevent the strap support from tearing and/or to provide a stable base for receiving strap tensioning force. A strap includes a first portion that extends along an interior surface of the strap support, a second portion that extends through the slot and around the slot reinforcement, and a third portion that extends beyond the slot reinforcement and toward a free end of the strap. The slot and the strap may be structured and oriented such that when the third strap portion is in an unfolded or untwisted condition, a portion of the strap support is sandwiched between the first and third strap portions.
