News for the financially troubled Crocs Inc. has been looking a bit less glum this week. The Niwot-based company's shares recently climbed 4.8 percent to $1.53 each, according to The Wall Street Journal. Yesterday, the company, which sells rubbery clogs, was also attempting to buy stock from its employees with an exercise of about $10.50 a share, writes the Denver Business Journal, which notes Crocs has also received a six-month extension of its credit with Union Bank of California. The company recently got a new CEO, John Duerden, a former president and CEO of Reebok International. In 2007, Crocs traded around $75 a share and were trading around $1 before Duerden's arrival.
