This is the second pair I have bought in the last 3 years. They last a long time and for someone who walks all day on concrete floors in a manufacturing facility I would recommend them all day. As with most new shoes you will buy in your lifetime, the first feeling is always GREAT. One thing I noticed, even after 12 months on concrete, the feeling was GREAT. Over time other shoes started hurting my ankles, knees and even lower back. At that point they will be replaced. I didn't have to do that with them, and I actually only exchanged them because the sole of one foot was worn out, and I was allowed to do that at my workplace :)
