Bought a pair earlier in the summer and so far the lightest shoes I have. I am no professional runner, I'm a newbie and I have to jog/walk through a 5K. But I pronate, always have, and have shin pain after only a few minutes of running. I bought these after trying them on at Lady Foot Locker. I tell the salespeople what I need but take it with a grain that they really know what they're talking about. This shoe was so light and breathable I couldn't weight to get my couch potato butt up and try them. I am very pleased. The flexibility is great and my shin pain is a lot less. 4 stars because, at least for me, my flat feet need more cushioning.
