How can make an athletic shoe at home?

Hello Core77

I have been reading the blog for a long time, but this is my first post in the discussion board. Your help will be greatly appreciated.

I am working on an basketball shoe project. I want to hand make my own working prototype shoe.

I have taken a mold of my feet to work off as a last. I am now in the process of hand sculpting what I want the midsole and outsole to be.
I want to use these to make a mold that i can then use to make usable shoe parts.
How can I do this?
What materials would you recommend to use for the mold.
And then how can I get liquid vulcanized rubber for the outsole and / or polyurethane for the midsole to make the parts out of.

Any help would be appreciated. I obviously need some.
