With the market uptrend now under pressure, Under Armour (UA) hopes continued growth in its moisture-wicking athletic apparel will also keep its stock from over-sweating. To help the company’s earnings growth stay on track, Under Armour is trying to aggressively grow its footwear business. Already, shoe sales jumped 50% to $122 million in Q3, up from $81 million in the third quarter of 2013.
