Bought these shoes two years ago for a 24 mile hike into the Grand Canyon with a 50 lb backpack. Very comfortable and good ankle support with a heavy load on your back. Waterproofing is good. Amazing grip on rocks and rough terrain. Since that trip I've been on many hikes and now it's become my daily work shoe and it's still very comfortable. Once these eventually give out I'll be back for another par of Keens.
