I've thought about getting a pair of Vibrams after hearing rave reviews from several folks at work. However, I am in the early stages of bunion development in both feet and I over pronate. A couple years ago, I ended up with a persistent bout with achilles tendonitis after wearing Nike Free sneakers (I didn't run in them, I was wearing them on walks). I, therefore, am leery of trying anything that might result in a foot/heel issue.
