Vibram Five Fingers

I was just looking at some video's on the Vibram Five Fingers.... http://www.vibramfivefingers.com/
I'm interested in trying them. More for going out and field practicing until my feet get stronger. I will definitely say they're not made to win any cosmetic awards.. they're funky looking. 
BUT ...for the people that have worn them disc golfing.. I and many others are curious:

( and many questions to take a stab at )

-Have you noticed less injuries to your back? ..  knees since you started using them? .. 
-Have you been more susceptible injuries out on the course than regular shoes?
-How do they hold up from the abuse of bad driving form (toe draggers) or concrete?  What about wet conditions?
-Does it hurt when you walk over sharp stones or roots?
-Do you recommend the KSO's or Trek's?
-Whats the life expectancy for a pair of these?
-Do they start stinking because you're wearing them barefoot all the time?
-Do they have insoles? .. can you replace them if there are?
-Is it annoying to wear these at tournaments because of constant questioning about them?

- Still more questions? .. well this is the thread to discuss everything about this product.
 

I searched the discgolfersrus forum and found comments spread all over the place... Here can be the central consensus of this product and how it pertains to disc golf.

I haven't got a full round in with mine yet because of the snowy conditions, but I will say my feet feel great in them. I have a pair of the KSOs. The first day I wore them was to work, after 8 hours my feet felt terrific, none of the normal sore spots, it was almost disappointing to remove them. I'm looking forward to seeing how they do on the course. Pointy rocks only cause mild pressure not pain (I stepped on a few just to check). My feet definitely like the all of the new input from the uneven ground.

I'll stick to my boots. There are some pretty big thorns around here.

lol. I might just try these for field practicing to start out with. If I like REALLY like them.. I'll try a couple rounds. Either way.. if I don't end up using them for disc golf... I could always use them when I go to the beach or tubing.

No way in hell. My buddy actually broke 2 toes wearing that shit, no lie.
