attn: shoe repair tradesmen: Where can I buy pebble driving moccasin soles for homemade driving sho

[newmember2010]

Looking for driving pebble soles like those found on Tod's driving shoes. I want to hand make a pair in ostrich leather but cannot find any place to source them. This youtube video shows an example of the rubber soles that I am looking for. They are basically a structured inside sole that extends through to the outside. Thanks for any help as I have spent 4-5 hours looking and have yet to find any information.
