Running shoes can be a little like friends. Some are strictly for fast times, while others are great when you're looking for a little more stability in your life. Take the Structure, for instance. For over two decades, it's been there, cushioning every blow and easing every transition, helping you navigate the peaks and valleys along the way. Now this legacy of a shoe is in its 20th year, it's faster than ever, and still there to support you -- wherever you want to go.
OK, BUT WHAT'S SO GREAT ABOUT THE 20?
