A quick, light race or tempo shoe meant to get you from point A to point B as quickly but as comfortably as possible. With no rubber on the bottom, the durability is a question but the speed and comfort is unlike any other race shoe.
I really wanted to love these because everyone raves about their Hoka's. However, these particular ones offered zero arch support and very little cushion. I did really like how light they were, but they gave me shin splints.
