Nike (NKE) may still be stumbling in China, but at least its sneakers aren't see-through. The world's largest sports apparel maker rebounded strongly Friday after reporting better than expected earnings late Thursday and mollifying investors' worries over slumping China sales. Shares were up 10% intraday in the stock market today. Other sports brands were running ahead, too. Under Armour (UA) bounced 4.1% intraday. Foot Locker (FL) was up 3.3%.
