These running shoes were worn by my husband for probably only 20 miles. He quickly realized they hurt his feet and he has since bought a new pair of daily runners. They are in really great condition. No holes or scuffs, and the tread is still completely in tact! According to the brooks website, these shoes are designed for road running, their midsole drop is 12mm and they weight 10.1oz / 286.3g. The cushion is designed to offer a smooth and floaty-feeling run thanks to plush cushioning. They are also a little more on the supportive side in terms of the spectrum of road running shoes. Priced to sell.
