I sell cars and spend more than 8 hours a day in them, walking on asphalt, concrete, stairs, on and off car ramps, through greasy service centers, etc. e shoes are on my feet 12 Hours a day at least 6 days a week since I bought them 7 months ago. Before that, I didn't have a single pair of shoes that would have served me longer than 4 months. I weigh 350 kg and they hold up great. 7 months on them and I'll probably easily get another 2 or 3. I'm hoping for a solid year and if they continue to wear like they used to it should be possible. As for the clicks reported by a customer in their review, I didn't notice that much noise.
