First, the most important thing to remember is that any shoe that you wear must have a thick, rigid and non-flexible sole. The concept is counterintuitive but the idea is that if you have a painful joint then the last thing that you want to do is wear flexible shoes that force motion through joints that can’t handle it. When it comes to the foot, less motion equals less pain, inflammation, and joint damage. A sturdy sole with no motion will also stop or slow the progression of bunions, hammertoes, stress fractures, and osteoarthritis.
Second, it is important that it has a soft, wide toe box, which will put less pressure on toes, which helps to prevent corns, ingrown toenails, and will even decrease the risk of developing toenail fungus. Obviously, sandals are a perfect option for decreasing pressure on the toes.
Third, all shoes that you wear should have rearfoot control (strapping) because shoes without rearfoot control force you to scrunch down your toes to stay in the shoe, which promotes hammertoes and mechanical strain on your tendons and ligaments, which can cause tired leg syndrome.
The fourth thing is to wear shoes that can accommodate a custom-molded orthotic or an excellent over-the-counter insert for better arch support, which will help with preventing knee, hip, and even lower back pain. These sandals do not accommodate arch support, so if you know that you need to wear your custom-molded arch support you are better off wearing enclosed shoes that will accommodate them.
