I really like these shoes, everyone teases me, but I walk more than 30 steps a day measured with a fitness tracker, on weekends I walk about 65,000 steps a day. I have no knee problems, blisters, calluses or coughing when I hit the 3-4 million step mark. I'm noticing a break in support, I can handle the 8 million step mark (6 months to 8 months). before I have to replace them. Annoying is the fact that the side foams keep falling out and aren't as strong as they were 4 years ago when I ran almost twice as much. but they are best for my extra wide feet that nobody else makes in the right size 4E 11.
