I'm a fan. I wear these to work all the time, hike in them occasionally, and even took them for a 5.5 mile run. I also love that they have slipper mode - good for rapid wardrobe changes in the parking lot. Just wish they came in a smaller size for the lady.
One note, the insole is very cushy. Some people may love this, but I wanted something more minimal. I swapped it out with a thin insole from some old cycling shoes and am now good to go.
