Sales slumped by 11 percent in the second quarter at LaCrosse Footwear, falling to $26.6 million. Net income plunged by 92 percent to $101,000 for the three months ended June 26. Outdoor sales declined by 2 percent to $8.0 million because of capacity limitations at Chinese factories, and revenues from work footwear dropped by 15 percent to $18.6 million because of the timing of U.S. government orders. Gross margins ticked up by 0.2 percentage points to 40.9 percent. LaCrosse said it will focus on addressing the supply issues that negatively affected its first-half results in the back half of the year. A new domestic production facility, expected to open soon, will significantly increase LaCrosse’s manufacturing capacity.
