I've worn this shoe hard for over a year now. I wore them for work both inside and outside, causually, as my winter shoe (don't go in ankle deep snow, obviously). This shoe has put up with my size and weight. I'm looking to replace them soon as I have broken the plastic heels at the back due to my laziness in not untying the laces. The tred is obviously worn, but still agressive enough to deal with some mud. Shoe is still even comfortable to wear after continueous use. The wide Keen toe box is amazing and allows my feet to feel like my toes have room.
