I've had these for less than 2 years. They were comfortable enough to walk on. But the floors are worn out. I've noticed that walking on gravel is uncomfortable. After removing them, I found that the bottom was cracked in the arch area. Completely torn in a few places. And on every shoe. I've done more than just walk around in shoes. These were my indoor work shoes when I didn't want to wear my work boots. But I'm in my 70's so I can't be that picky about shoes lol. I'm not impressed with the quality of these delays.
