I purchased these for a trip to Peru and wore them for two weeks right out of the box. We walked miles each day over varied terrain -- city streets of Lima, Inca ruins, steep steps of small Andean towns, all over Machu Picchu and dirt paths on islands. I wore them instead of my heavier hiking boots for a 4 day trek in the Andes and they were perfect. Good support on uneven surfaces and lightweight so I didn't tire at altitude. They are not waterproof so it was a good thing we were there in the dry season.
I need a wide toe box and usually the Merrill brand does not work for me but these were so comfortable that I plan to order another pair. Can't wait to wear them on the tame streets and paths of home!
