Lone Peak is a legend in the trail community! The 4.5 version comes with some exciting updates, while retaining the original feel that many of us love. The upper has been trimmed down for more flexibility and comfort. The lacing system has been simplified to facilitate small adjustments over the foot. The midsole material has been adjusted to give a more resilient feel to the foot while having a built-in Stoneguard ™ for extra protection against sharp stones.
