Don't women like to try on shoes before they buy? I think that they do and you are going to have to provide for that with your business. This probably means offering free return shipping if the shoes don't fit, or match that special dress etc.

I think of all the possible web based businesses out there women's shoes is likely the most difficult.

Just my opinion.
