Not necessarily barefoot, but it may be that too much cushioning can actually cause injuries. Runners who wear cheap shoes statistically get injuries less often than those who wear expensive shoes. So, there are some fancy new shoes out that aim to provide better traction and protect your skin from abrasion, while having a minimal amount of cushioning between your foot and the ground.http://www.wired.com/wiredscience/2009/07/barefoot/
It's interesting if you take a close look at the heel strike of a traditional running shoe vs. a pair of these new minimalist footwear:
The new footwear, although it looks weird, does appear like it is softer on the ankle. If it became a new fad, like crocs, I'd buy a pair.
What footwear do Buddhist monks typically wear? Jesus sandals?
And what shoes do you wear?
Definitely the most uncomfortable shoes I've ever worn was a pair of big, black, steel-toed army boots I used to wear. The cushioning wasn't very soft and they were heavy, so it wasn't a very good work boot.
