Durability ensures that your hiking shoes can withstand the rigors of the trail over time. A more durable shoe will last longer and provide better value for money. The KEEN Targhee IV has a slight edge in durability, thanks to its glue-free construction that resists delamination and a more puncture-resistant outsole. While the Altra Lone Peak 9+ offers a reinforced toe box and MaxTrac outsole, some users report that the lugs wear down faster on rough surfaces. This makes the KEEN Targhee IV a more reliable choice for those who need a shoe that can handle extensive use.
