The Dow Jones industrial average sank nearly 1,000 points yesterday in one of the "wildest days ever" for financial markets, writes The New York Times on its DealBook blog . Nervous traders, the faltering Greek economy and riots, a major trader error, and central bank complacency all seemed to work together to create one heckuva a panic. But one interestingly positive story has emerged from yesterday's dust---the continued success of Niwot-based Crocs . As stocks everywhere shook, Crocs---the maker of popular rubbery shoes---posted a first-quarter net income of $5.7 million, or seven cents a share, according to the Denver Business Journal . Compare that to a loss of $22.4 million, or 27 cents a share, for the same quarter a year ago, and it seems Crocs is on the mend. Crocs' retail sales are up 23 percent for the quarter; wholesale sales rose by 26 percent, and online sales were up by five percent. It's quite a turnaround for a company that was once struggling hard . To get an idea of the company's history, including past internal troubles, read "Burning Rubber ," by 5280's Robert Sanchez.
