My dad is continuously saying his feet are killing him. He has to wear size 14,steel toe work boots all day from 10 to 12 hours. I could only imagine the pain he feels. On that note I decided to purchase these SLDHR Soft Silicone Comfort Shock Absorber Insoles hoping they will give him some relief. So the other day he came in from work bragging about how much better his feet felt and has came home for the past week say they get better every day. They are super cushy and the gel just gives the best comfort. Here is the link you should check them out. https://www.amazon.com/SLDHR-Silicone-Insoles-Athlete-Replacement-Unisex-adult7/dp/B074FK9NBJ
