Made with one of the best foam cushioning designs in its class, the shoes are really made for durability. Even after two months of intense running, the shoes are still bouncy and the foam is not compacted. With a flexible upper, the shoes are not the most supportive of the midfoot. It is an area I would like to see improvements in future releases. But with a breathable construction, the shoes feel great and they represent a solution for everyday running. However, if you are a midfoot runner, you might feel that slight lack of support when running at higher speeds.
