The shoes are great for high mileage. They don’t require break-in and they are made with a good fit. For my running needs, it represents a comfortable option. Since I come from the previous Supernova, I also feel the shoes are a worthy upgrade. They feel more stable and part of these improvements is actually based on the heel. With a stronger heel counter and a larger heel cushioning, the shoes almost feel as stability designs. They are recommended for those who need that extra security while running, especially on wet surfaces.
