Best orthotic I've ever worn...period ! I've tried nearly every over-the-counter orthotic and gel insole and they don't give anywhere near the support I feel with SelectFlex. I felt it the moment I slipped the orthotic into my sneaker. My feet and legs now feel refreshed at the end of the day, WOW. I don't like having to switch the orthotic into other shoes and feel the difference when I don't have SelectFlex in my shoes.......will now need to buy a few more pairs.
