This invention consists in a novel process of
making platform shoes of high‘style with com
fort features. The process of my invention re
sults in the production‘of shoes having this un
usual combination of characteristics: viz., the
stylish lines of a shoe designed primarily for
style and the cushion features of a shoe designed
primarily for comfort. My invention includes
within its scope the novel shoe construction here
in shown as produced by my novel shoemaking 10
process.
platform, suiiicient to support the toe joints of
the wearer's foot. This makes the shoe comfort
able by providinga cushion under the ball of the
foot, while providing a solid foundation under the
toe joints, thus relieving them ‘of the resilient
pressure of the cushion.

Another important characteristic of my proc
ess is that the ball end of the platform is solid
and intact during the ‘steps of attaching, trim
ming, and edge-setting the platform. It is only
