An apron is a piece of leather material that covers the top of the vamp around the perimeter, almost like an apron that you might wear. It sits just in front of a shoe’s lacing system, and then is connected to the vamp leather with a stitch. Typically, this does not extend to the end of the toe. The apron toe features a seam that starts at the middle of the toe, runs around the shoe, and ends at the middle of the heel.
