Abstract: A unit sole construction, including a sole body of molded, rubbery material, and a welt extending along the body, the welt having an exposed upper wall portion, and a tongue portion extending from the wall portion into the body, the tongue being embedded in the body to secure the welt to the body.

Abstract: Apparatus for testing footwear soles, comprising a frame, treadmill supports mounted on the frame for movement along an axis, a treadmill assembly mounted on the supports, the assembly including an operative treadmill surface movable in its own plane along a direction transverse to the axis, resilient means connected to the frame and the supports for biasing the treadmill surface in a rest position and for resiliently opposing movement of the surface along the axis away from the rest position to a range of operating positions, a shaft mounted on the frame, the shaft being located with its longitudinal axis parallel to the operative treadmill surface and spaced from the rest position thereof in the direction away from its range of operating positions, a drive for rotating the shaft about its axis, and a sole support mounted on the shaft at a distance from the shaft axis sufficient so that when a sole to be tested is installed on the sole support and the shaft is rotated by the drive the sole support will carry

Abstract: Footwear lasts are molded by preparing an oversized model of the last to be molded; isolating, applying mold release to, and covering with liquid ISP at least first and second surface portions of the model; allowing the ISP cure to form at least first and second mold portions; and using the mold portions to mold plastic lasts.
