Its on a pair of classic huaraches i have here, bought them many years ago and never worn them, was a limited edition, and i think maybe japanese related?
The little bit in the centre is supposed to be moon shaped but my paint skills are limited! :D

they also have 3"26"00 stitched into the inside, im guessing its a time for some sprint, lap, race or something.
i got a pair of huraches which are also limited edition, imports
they have some crazy ass symbols on but i never really bothered to find out
huraches are usually worn playing basketball
thats why i got mine
