Interesting article on today's New York Times:

"across the board, motion-control shoes were the most injurious for the runners. Many overpronators, who, in theory, should have benefited from motion-control shoes, complained of pain and missed training days after wearing them, as did a number of the runners with normal feet and every single underpronating runner assigned to the motion-control shoes"

I suffered the consequences of being recommended a motion control shoe once --- 3 runs with those shoes followed by 1.5 years of plantar fasciitis. Never again!
