Help!: Bicycling road shoes

Hi all,

I am just starting out road cycling.  However I have a small problem.  I have cerebral palsy and my right foot is several sizes smaller than my left.  Therefore I will need to purchase two pairs of road shoes.  I trying to find a good/reputable place where I might be able to get them at a cheaper price as I cannot really afford two pairs.

Thanks for your ideas and help!
