Both my hubby and I definitely need a very comfortable insoles. We have an upcoming 20+ hour trip abroad next month and comfortable insoles would help us a lot from those long walks in the airport. Actually, I bought a pair shoes that is only intended for long trips right after I got back from my trip in the Philippines last year. My feet swelled up and that was probably because my shoes did not have much ankle support on them. You can find spenco insoles here. I will check it out more.
