I also just bought a new pair of running shoes which is always exciting for a runner. I got the new Nike Skylon 11, which is a show based off of the Nike Free. The main difference with this shoes is that it is a very neutral show or is does not provide a lot of support.
More runners have been going to this more neutral shoes or minimalist shoes because they actually help to strengthen the foot and allow you to have a more natural running form. The way they work is the sections are allowed to move independently which allows more flexibility in the shoe which is a more natural feel and does not restrict the foot as much. I have done one easy workout in them, 5 miler on the treadmill and so far I love em. But the real test will be my first 20 miler in them. They are very light weight and feel like there is nothing there, which is a good thing.
