Comfortable, lightweight and fun to run fast in. Perfect fit for my feet. Chose to use them on my first ever half marathon. Did a few test runs in them beforehand and loved how they felt. However, halfway through the race I noticed a loud snapping-sound from the left shoe. At first it sounded like something was stuck underneath, but the sound was non-stop until the finish line. A friend of mine told me that he had read about a fairly common problem with broken rods. After looking it up myself, I'm pretty sure this is what happened to my shoe. Contacted Adidas who said they wanted to send me a new pair. However, these shoes is no longer to be found on Adidas' website so they could only offer a refund if I chose to return the shoes. Since I bought them on sale I only get my the amount I primarily paid in return. Which is fair enough - but for me, this means that I have to find new racing shoes and pay full price. Bit of a struggle if you're unlucky like me. As I said, great shoes that I were going to highly recommend - until they broke. Now I'm not so sure anymore.

This is a very Great shoe, very light and great energy return
