I bought these last time they were available here. My first pair of Vibrams, after having wanted a pair for a couple of years. ($100 price tag wasn't happening!)
My thoughts are as follows:
If you're looking for a pair of barefoot shoes, this isn't the model you want. The soles are thicker and more sturdy. You don't get the amount of movement & feeling you do with some of their other models.
You really do need to measure your feet to get the correct size. I saw a few size comparison charts and, if I had followed them, I would have wound up with a shoe that was way too big for me. Measuring, though, gave me the perfect size for my foot.
Vibrams do work for wide feet. I typically need either W or WW, but because of the way these are made, that's usually not a problem, except..
This particular model can be really tight across the top of the foot. Supposedly, if you wear them enough, you can break them in to the point where that's not a problem.
If you're used to being barefoot, you still need to get used to wearing Vibrams. The learning curve might be less steep, and might take less time, but they're not quite the same as being barefoot, and your feet do need some time to adjust.
After purchasing this pair, and giving them about a week to figure out what I liked, I wound up buying a pair of Classics from 6pm. I honestly like those a lot better, but I'm not a runner - I just needed a pair of shoes to wear when I'm not barefoot (which I am 90% of the time.) I've since broken in my Classics, and love them to death, but my Bikilas are still tight and a bit uncomfortable. I will definitely be buying Vibrams again... Just not this model.
