I deliver mail for a living so I usually walk somewhere between 5 and 15 miles a day, every day, 6 days a week, no matter what. These shoes withstand quite a beating. And they're without a doubt the most comfortable shoes I've ever owned. The way it is constructed, the shoe eases your natural stride, so it actually makes you walk more quickly and efficeintly, not to mention much more comfortably. The velcro is nice for me because I can't exactly put down 20 or 30 pounds of mail to tie a shoelace that might be rain-soaked anyway. If you work on your feet all day, I cannot honestly give you a better recommendation than this shoe.
