I need shoes, preferably under 70$, that are light, flexible(flex groves), and can take a lot of mileage. I brought some Asics Lyte 33 a while ago and they are the lightest shoes I ever owned. Only weigh like 7.8 ounces! I'm looking at the Nike free run 2, anybody try these? Any more suggestions for light, flexible, cheap shoes appreciated. I'm just what people her call a "hobby jogger"
