Does anybody own any of these "Piper's" GBs advertised as being more comfortable, like these listed here? http://www.kilts-n-stuff.com/Highlan.../ghillies.html I've had a classic pair with leather soles for years and they have never been comfortable. I have no arch and typically wear orthotics, which probably explains why the ones I own are not that comfortable. Do any of these others have removable footbeds? Do they at least have a built-in arch of some sort?
