Footwear group K-Swiss Inc has posted an 81.4 per cent increase in fourth quarter net earnings to $8.68 million, up from $4.78m in the same period a year earlier.

The company, which produces footwear under the Royal Elastics trademark and its namesake brand, also saw total worldwide revenues rise 51.2 per cent to $80.43m for the three-month period, up from $53.18m in fourth quarter 2002.

Describing the results as "impressive", chairman Steven Nichols said the company looked forward to a prosperous fiscal year ahead.

"The K-Swiss brand and our commitment to its long-term health and vitality are the driving force behind every decision we make," he said.

"With the marketing campaign and product offerings we have planned for 2004, a brighter outlook for continued improvement in international operations due to previous investments made and continued demand among retailers and customers, we believe a strong foundation has been set for another strong year for K-Swiss and our stockholders."

K-Swiss is based in Westlake Village, California.
