the nike wovens are nice but will you be able to get all the sizes that you need? nike id you will but might be too expensive, the vans solutions sounds the cheapest. but still 50 $ a shoe.

what type of shoe are you looking for-can it be any type of shoe as long as its orange and white??
maybe you could go this route-$24 (yellow-there has to be an orange and a white sole maybe)
a sandal-not bad-$39
