I love these shoes so much.
The best parts:
* They are extremely lightweight. They weigh less together than one of my other sneakers. That makes them the ideal sneaker for throwing in my suitcase while traveling. In a pinch, I've even used them for running, by using barefoot running techniques (note that I'm not actually recommending that you do this).
* They are narrow. I have relatively narrow feet, and I fit easily into the standard width shoe.
* They come in a wide range of sizes. I am a size 12, and I appreciate that NB extends it's range that far.
* They are striking-looking. The body of the shoe looks like it's made of felt or boiled wool. I have gotten so many positive comments from strangers on these shoes. People love them.

The downsides:
* The recycled material is not as durable as some sneaker material. In particular, it tends to pill up. This did not detract from the shoe for me, because the heathered color disguised it well. But others may disagree.
* The shoe is not water resistant. In any way. It leaks where the upper meets the sole. You should think of it as having the water-resistance of a mesh shoe.

On the whole, I love these shoes so much that I bought two back up pairs. Which is good, because New Balance has decided to discontinue them. I'll probably try the new version, even though they're not made from the same cool felt-like material.
