The only reason why I got the Vibram Five Fingers were my bunions on both feet. I didn't really think about the other benefits of walking barefoot, but it really seems to be interesting.
I got my KSOs three days ago and just took a few walks where I usually go running. On the way to that area it's asphalt and pavement, then it's gravel and some forest tracks. When I was 7 I started Tae-Kwon-Do and quit when I was 18/19. Back then we also did outdoor barefoot jogs through the snow. Anyway, I can really tell that my feet are not used to walk barefoot anymore.
In my normal shoes and my running shoes I've been wearing orthodics for years to conquer my flat and splayfeet. Had them in normal shoes when I was a kid, but didn't need them in running shoes (according to my doc back then) since those supported my arch enough. When I had some knee problems a few years ago I got orthodics for my running shoes, but also changed my running stile to a more mid-foot strike and also a way more smooth body motion. I'd say I'm more conscious when running and listen to my body. No heavy heel strikes anymore, not even when I'm running downhill.
Anyway, getting back to the bunions. I have them since I was a kid and actually always thought that would be normal. I just remember one time when I Tae-Kwon-Do examiner complained that I wouldn't take it seriously since I wouldn't have the correct foot placement during the basic position. A few months ago I somehow read something about bunions/hallux valgus and decided I may have to do something about that one day. In the beginning of May I did a 20 minute run on a small island with the majrity being sand. One the one hand I didn't use my normal running shoes and on the other I hadn't run on sand in years. Afterwards and also the next day I had lots of pain in the joints of my big toes while walking. That's when I bought the bunion aid splints from Hallufix and have been wearing them nearly every night since then:

Feet loose on the ground:

Flexing the toes:

Toes were aligned by hand and then the feet were pressed to the ground:

When my feet are loose on the ground it still looks pretty close to the first pic. When I flex my toes while standing and then let them 'down' on the ground again I can clearly see that the toes are aligned like in the 3rd pic with the big toe on the right foot even pointing straighter forward. That's amazing and I never thought that it would have such a positive effect in such little time. There's lots of work needed on my left big toe though. When flexing the toe the direction in the joint is way more off than on the other one.
I'll continue to wear the Five Fingers in all day situations and for walks, but I'll continue to run in my running shoes with orthodics and will also wear shoes with orthodics. Maybe I'll get some classics for when I'm home since I guess that they're easier to slip in. I don't have any problems getting my feet into the KSOs though.
I don't care if it's impossible to correct the bunions fully, I just wanna do something and don't see the need to undergo an operation (yet).
I'll post some picture of the effect that the Vibrams in combination with the Hallufix splints have on my feet in a couple of weeks or months.
