If they _do_ hit outlets, Mel, they'd most likely hit outlets in the USA. On the odd occasions that rarer stuff hits Nike outlets in Australia, they're often snapped up by staff and never hit the sales floor ):

eBay really would be your most realistic option, I'm afraid.

Nike men's sizes start at 7.5, Mel - that'd be the smallest size you'd find (6, 6.5 & 7 are all kids' sizes, and they wouldn't have been produced in kids' sizes).
