The general price of the shoes is based on two things: the design you choose and how long it takes me to do it.
On average the price for Chucks (Low top and High top) is only $20 + The cost of the shoe (Unless you have your own pair in good condition that you want me to paint [you also have to know me personally-- or live in Ontario so you can ship them to me]). Otherwise I have to buy the shoe from a store (Until I can order the shoes from someone else in abundance) and that price is added. Typically I can get a pair of shoes for $40-60 (Stores are ridiculous in their pricing.. Gah.) So a pair of painted chucks would cost around $80 dollars + shipping if you live outside of Ontario Canada (or if I know you I can just give them to you.. good old school).
The pricing for boots is more as they are about four pair of high tops in one. My price is, on average, $40 for the artwork plus the cost of the actual shoe--unless you have your own, and live in Ontario, yadda, yadda. .. .. The pricing of boots varies depending on the size of you're foot (For some reason male and female as well) so if you're looking for a pair of painted boots I have to pay more at the store to buy your shoes if you have large feet (cruel, I know).
So there is an art cost and a shoe cost. And this sums up the cost. Any questions-- you know what to do. Email me!
