Leading footwear retail chain Brown Shoe Co Inc on Tuesday posted a 19 per cent climb in first quarter net income as its results were boosted by bumper sales of Spider Man-related children's shoes. The St Louis-based operator of around 1,340 stores said its earnings for the 13-weeks ended May 4 rose to $7.6 million, or 43 cents a share, from $6.4m, or 36 cents a share, reported in the same period last year.
