Hi there I'm a newbie here from Pittsburgh. When considering an orthotic device, one should be evaluated by a podiatrist, not a salesman. A thorough biomechanical exam evaluates your specific gait pattern and joint motion involving your lower extremities, your foot type, muscle strength, age, activity level, and shoe gear will also be evaluated in order to properly prescribe your foot orthotics. They offer CROCS & OTC Arch Supports that you can try on! It's so nice to wear them especially when you want to walk for the whole day. I swear that you would love it and you won't regret it.
