In this version, the Stoneguard is lighter for you to enjoy even more the tremendous flexibility of the shoes. Try using the Stoneguard and they will protect you more on rocky routes than annoying stones. On milder trails, you can remove them and further reduce the weight of the shoe. The midsole is made of Quantic, an extremely lightweight material but also very soft to the touch.
