Go old school like they did many moons ago. I recall years ago (1980's?), some fellow showed me a crusty pair of bike shoes. I recall how we both laughed as all they were just leather dress shoes with the heel removed. However between the insole was a patterned wood piece with the grain running heel to toe. The cleat's were partially gone but was a cobbled piece of wood attached by screws from the inside (head facing the inner sole). Simply a dress shoe with stiffened sole.
