With one of the most unique designs ever tested, the shoes feel really comfortable. Made with EVA foam, they feel great on the feet. But after a few hundred miles, you will start to see wear on the foam outsole, typical in the shoes with this design. The fit is great although runners who have narrow feet might feel they are a bit lose. At the same time, running really fast with the shoe can be a challenge. It is why they are recommended for long-distance running where the soft foam can really show its full range of benefits.
