Inspired by xc-Dan's article on the failure of modern running shoes to keep us from injury I pulled out my freakish Vibrum Toe Shoes (
http://www.vibramfivefingers.com/) and did 45 minutes in those crazy things. Then another hour and a half in my NB 790's about the lightest shoe you can get. All this talk about cushioning, stability and control is pretty far fetched. Feet know what they're doing; let them do it.
