Out of the box, they went 2 days in the Gila Wilderness (hills, water, and sand), 1 day at White Sands (yes, in the desert), 2 days at Guadalupe Nat. Forest, one day of horses, and one day caving at Carlsbad. These trips were very aggressive day hikes. Excellent fit, true to size, no problems, and absolutely perfect. Tight heel, good arch support ,and good toe room. Better than Breeze, more robust wrt rocks and water with the same firm heel and arch. I tried 7 different sets and ended up with these as the best for the performance and cost ratio. These are great day hikers or light back pack shoes. They are not too hot and seem to be more robust than the Breeze with the same sole. I am from the Southeast, a runner, and these are perfect for here, and they survived NM.
