Another U.S. shoe retailer, Shoe Carnival, thanks the warm weather in February and March for a 7.3 percent increase in same-store sales during its first quarter, driven by sandals, canvas casuals and boat shoes. Traffic in its stores rose by 5.4 percent. The result was a 12.2 percent overall sales increase to $222.6 million for the quarter, leading to an 11.1 percent increase in net profit to $11.0 million. The number of stores rose by 10 doors to a total of 336 during the three months. Another 11 new ones are planned for the second quarter, including the chain's first store in Puerto Rico.
