i somehow really doubt that 2% of the world's golfer's would buy those shoes eventually. this is assuming that even if 2% of the world's golfers bought a pair of these shoes, they would buy one each year.
you also have to consider that this golf shoe is just one of many different shoes they sell, so that even if they sold a crapload of these golf shoes, it'll only add a little to the overall bottom line.
it's kinda like owning 50 stocks, and having one of them double in one day. it's a great thing, but it's not going to significantly increasing the value of your holdings by a crazy amount. what's more important is the overall quality of the whole crocs line of shoes and how well they sell as a whole.
