Looking for some help in finding the base boot that was used to create Supergirl's boots for the show. I'm assuming Colleen Atwood built the boot around a normal shoe like she did for flash and arrow, but I can't seem to match it. The sole of the boots seem to be pretty unique, but I can't seem to come up with it in searches. Any help anyone can give would be greatly appreciated. Check out the bottom of the sole below.
