Notably, the domestic business has been especially weak, seeing sales decline by 3.4% in the most recent quarter, which has pressured profits. The footwear market has been getting more competitive, and rivals like Under Armour (NYSE: UA) (NYSE: UA-C) and Nike (NYSE: NKE) have seen profit growth slow. Both companies' stocks are trading near 52-week lows. A resurgent Adidas also seems to be grabbing share.
