Stay low limit bouncing and keep your strides short-Really works like Texas84 said. You will be amazed once you run mileage how much of a difference it makes.
Also, the best tip I ever got was as important as the shoes you wear are your socks. I love my running Thorlo's. Made here in NC and the best socks ever.
Are those compression socks? I have those but not that brand. I have noticed a tremendous difference already.
