ABSTRACT:
A flexible strip divides a shoe sole into toe and instep sections. Toe deflection means lifts the toe section when the shoe is in a weighted state. Toe deflection means includes a toe plate coupled to the toe section of the sole and an instep plate coupled to the instep section of the sole. The toe deflection means pivots the toe section of the sole about the flexible strip by applying bending forces to the toe and instep sections of the sole.
