These are fantastic, I'm planning on buying a second pair. They are light, fit the foot well, and have a great lacing system.

They certainly feel different at first, and it was odd for me to walk in them until I went up hill. I live on a mile high hill that's a 20% grade the whole way up. It's always a work out, but in these shoes it is much easier on my muscles, knees, and lungs. After the hill, walking on the flat was far more intuitive.
