Dear foot scanning addicts.

I would imagine that loose fit standard sizes, combined with air / foam
bladder techniques will always be far cheeper for manufacturing people
specific shoes than using scanners and milling (which would require further
processing to attach the upper fabric etc). I believe that companies in the
US are already using the foam version for Football helmets where fit is
safety critical. I am sure that with a little more R&D into material cure
times and properties this will also be the way forward in the shoe industry
 - if indeed there is a mass requirement for anything other than a good pair
of socks/insoles (inflatable or not).

As a thought, wouldn't the most accurate way be to place the persons foot in
a mould with the outer tread form on its surface (the cavity half), and cast
into the 'tool'. This would provide a perfect sole (toe nails, warts and
all). If your worried about burning your toes then use a high density pin
tool (with membrane) to seperate skin from polymer.

Perhaps you're aware that Cyberware (Monterey, Calif.) has had a foot
scanner for years.

Interesting, although it sounds like a data collection project, not an
effort to popularize the idea of scanning feet and quickly and
inexpensively producing custom-fit inner soles or supports for consumers.
