Yea, but those they sell nowadays are very thick right? Tapered towards the toes?
That's the whole point!
Thick that's why they are comfy.
I usually buy shoes with removable insoldes nowdays because they don't last more than a year.
Edit: there are some places that do sell insoles that are orthopaedic in function. I remember I got my pair at Novena Medical Suites, one of the shops. Damn comfortable as well.
