I work long hours on concrete surfaces and I'm on my feet the entire time. My tool bags are heavy and I'm carrying heavy material as well. I have tried every insole possible over the years trying to make my feet comfortable while working and nothing has really ever worked all that well.
The super feet insoles were what I had ended up using for a long time but I wasn't happy about it, they still hurt, just not as much and the outside heel of my boot sole still wore out in 3 months. You know how quickly work boots wear out on one side but not the other. I finally tried these insoles, after much procrastination due to the price, and I am so happy with them.
My back and knees feel great, my plantar fasciitis isn't noticeable and my boots no longer wear out unevenly, which has prolonged their life from 3 or 4 months to 6 months and counting which essentially makes the insole pay for itself considering good boots are $200+ these days. I even bought a pair for my coworker who's had hip and foot surgeries and it helped him as well.
