Like some other American shoe retailers, Shoe Carnival posted poor results for the 2nd quarter ended Aug. 4. Citing a decline in customer traffic, the 285-store chain reported a 7.1 percent fall in same-store sales for the period. Overall sales increased by 5.4 percent to $154.8 million, but the company conducted an aggressive clearance of its Spring and Summer merchandise, leading to a 94 percent drop in net income to $167,000.
