How would I handpaint my Dansko clogs?

I stumbled across this site with a line of cool hand-painted clogs I haven’t seen elsewhere. Loath to buy something I could do myself, I wondered could I pull this off? What kind of paint? How to seal it to preserve the design?

Or just break down and buy a pair?

And does anyone else see “Easy Shipping, Easy Felching” next to that dog’s head? :eek:
