My feet were killing me and no shoe was helping, so I took my moms foot Doctors advice and looked them up on line. Now no more achey feet at the end of the day. I can still where my low heels for a while and buts out in to my Asics. Great price and definately perfect otho protection shoe for your instep, and heel, as well as great on the old back...Thanks to the seller and to Amazon for making shopping so easy...Thank You
