i don't know who carries them.
i recommend getting a neutral shoe (in your size) and placing custom orthotics in them. this would be far superior than buying a motion control basketball shoe.
a custom orthotic is made from a cast taken from your feet. they will give you the arch your body will allow. also, the orthotics can last for several years. shoes don't have much longevity and may not maximize the support your foot needs.
