Footaction has Adidas Stan Smith Originals (multiple colors) on sale for $29.99, normally $80-$100.
Note that shipping is a steep $7.99 if your order is under $50. BUT… if you join their email club (it's free), they offer standard shipping for free on all orders. If they show up and they have the glossier leather and the fatter, textile backed tongue and you DON'T like them (remember, they're, y'know, $30…) then I'd contact customer service and get a free return. Because that certainly doesn't appear to be the pair they've got on their site. Thanks to Dappered.com for the tip!
