Now I have bought 3 pairs of these. These are the most comfortable walking shoes I've ever found (and I walk about 15-20 miles a day on a treadmill). THE MOST IMPORTANT THING YOU SHOULD KNOW is that there are two versions for sale here. One version is "Made in the USA" and the other version is made elsewhere. You can easily tell which version it is because the US version says "Made in USA" on both the back and side of the shoe. The non-US version is more convenient but less durable. The US version is also about 1 size smaller. I like to wear both about the same. The US version is better for running, the international version is better for walking. See image.
