yeah hiking boots would be purfect
OR you could probably make them by getting white rain boots! cut them and well.. do this
First i guess u gotta sew down the front middle(if u wanna go for the boot shape thats visible in the 2nd pic.)then u basically paint the bottom pink, add a loop for a belt, and sew in some pink on the front of the boots. after that, all thats left is making 2 pink belts to go around the shoes. woah i made that sound easy.lol it probably is. just dont forget to sew the edges of the top of the boots afterwards like in this pic(its barely visible but its there) otherwise it might tear. i think this might work i have no idea about modifying shoes or anything but
this seems like what i would do. only problem would be- where do u get white rain boots?
