A kinesiologist in my department offered a gait analysis and it turns out I've got severe underpronation meaning I basically walk on the outside edges of my feet. The wear pattern on my shoes (and my garden of ingrown calluses) seems to bear this out.

After snooping around there seem to be two ideas for this:
• going barefoot/minimal will condition me to pronate more
• it's permanent so use rollbar or stability shoes to avoid pelvic damage

Both options seem equally expensive (and equally hard to find in 12EEEE).
Any experience or knowledge with this issue?
Thanks!
