There are a couple of ways that this can work:

FIRST
-we figure out what exactly you want on your shoes, and a price based upon the design and time involved

SECOND
-you get a pair of shoes (or if you already have a pair of shoes, even better!)
*this method is preferable in that you are able to ensure the shoes fit properly 
**TIP: Norsdstrom sells TOMS, and does free shipping with all online purchases

OR

-choose a canvas shoe option:
-TOMS shoes

-American Apparel (made in the USA) lace-up tennis shoes
http://store.americanapparel.net/unisex-tennis-shoe_tennishoe
-Vans “Original Classic Authentic” lace-up style
http://shop.vans.com/catalog/Vans/en_US/category/classic-shoes/authentic.html?cm_re=classics-_-
*please inquire if you have other shoe option requests

THIRD
-i send you an invoice for payment through PayPal
(you do not need a PayPal account to be able to pay by this method)

In about 2-3 weeks later you have your own custom painted shoes!
