30 years in corporate America, never touched work boots in that entire time. Decided that I wanted a change and got a logistics job at a car manufacturer. 10 hours a day standing or walking on metal or concrete; constantly stepping on and off of equipment. I thought my feet were put in a grinder. These insoles have helped to fix the issue. These are really good insoles I highly recommend them. I have started back taking my dogs on a mile walk each day after work like I was doing before I started this job.
