Hand painted shoes based on periodic table. Design includes atomic symbol and number as well as key at the toe. Each pair will be one of a kind due to size of the shoe and orientation of the symbols. Not every pair will have exactly the same canvan shoe used as the base--I buy whatever the local store has in stock at the time of your order. Things that could differ from shoe to shoe are orientation of the seams and eyelet color--however, the basic design remains constant.
