I work in retail and I'm on my feet for 9 plus hours 6 to 7 days a week . This is spent walking on concrete floors. My feet and legs had started burning and hurting really bad about 2 months ago. I'd seen the advertisement on Facebook for the inserts and was cautious at first. The more I researched I decided why not try them? Well, I will be the first to tell you that I was shocked as to how much these helped my feet and legs. I'm going to order 2 more pair because I go home and don't have to soak my feet and actually feel like working outside in my flower garden! Thank Protalus!!!
