What I liked is how comfortable these shoes are to wear from the start. I recently started walking 4 miles a day (every single day)My prior new shoes wore out within 2 months, 200 miles on this regiment, and I had foot pain starting to develop at my big toe joint with the old shoesThese shoes relieved that pain from the first time I used them. About 1 week, 30 miles in and they are still working great.08/20222 update, these only lasted about 2 months before I started getting blisters, I think they stretched out over time and began rubbing, also the air cushion soles developed leaks over time, replacing with a solid cushion sole shoe in the future.
