Abstract
A novel sport sandal construction capable of immediate tightening or loosening adjustment of all strap portions relative to the foot, with one quick adjustment. A control strap is anchored to a ring on one side of the sole at the ankle region, extends forwardly with a slip fit through a centrally located ring on the forefoot strap at the metatarsal region, then rearwardly to an anchor strap ring on a second anchor strap at the outside of the sole, and then through this ring with a slip fit to double back forwardly and overlap the rearwardly extending portion, where it is adjustably fastened with hook and loop fastener strips. A heel strap also extends between the two anchor strap rings. A simple length adjustment of this control strap simultaneously adjusts not only the length and position of both strap portions on both sides of the foot, but also adjusts the distance between the heel strap and the center of the forefoot strap.
