I have a pair and love them. A friend also has a pair and it took her some getting used to them; when you walk “barefoot” you use different muscles, so she was sore for a while. But I go barefoot more than I wear shoes and while walking in shoes for long periods makes me sore, walking in these was no change.
I have extremely long toes. Really. They are like fingers.
I love my KSOs and plan to run in them a lot this summer.
I have the KSO’s and also do not run in them although the idea is intriguing. Generally speaking, I hate-hate-HATE running as the method of getting exercise. Any-hoo, for general wear I find them fabulously comfortable. I also use them for sand volleyball in the spring and fall when rain and low temps result in very cold feet. I’ve not found them to be the greatest at insulation from the temps but they are fantastic for maintaining that “bare foot” feel in the sand.
For you vibrams runners - what surface do you run on? I just cannot imagine the beating my feet would take running on the streets/sidewalks of my neighborhood. So, treadmill? Running track? Cross-country/Trail running?

How hard was it to get used to all the between the toes material? I spend waaay more time barefoot than shod and would love to try these. I’m guessing it would be about like getting used to the first pair of flip flops of the summer? I’ve been eying these shoes for a while, would love to take a pair for a test walk.
To be honest, I never had to “get used to” it. It was just… natural. I suppose to provide a bit more detail - the material between the toes is incredibly thin and like the rest of material it is stretchy. My pair do not bunch up or anything. I never even notice(d) the fabric. Not at all like flip-flops which generally have a fairly large and noticable piece of material between the two toes.
It does take a few times to get used to putting them on and getting your toes into the right place tho’.

This is so true! Unfortunately in my circle of friends the reaction has primarily been negative with “OmiGod that is so gross!” being the most common type of refrain. shrug F-ck 'em, I like 'em! Haha.
I bought a pair as a result of the thread linked earlier, and I love them too. I started working out in them and the first thing I noticed was OMGMYCALVES. My calves were apparently being forced to work for the first time ever, and it was a shock for sure. But now they feel great, so go for it!
I found a store less than 20 miles from me. I want to go try some on. I’m due for a new pair of shoes. I noticed some fine print that says they’re machine washable? That would be great.
I own a pair that I can’t wear/ I even went to a store to try some on first, then bought them much cheaper online… but from someone with no returns allowed.
Important things to know about fit:
– Each style the brand offers fits slightly differently, I think because of the materials used having different stretch properties.
– They are unforgiving for non-standard toes. (My own problem: Toes on one foot fit exactly right, but toes on the other foot… well, the toes, themselves, are about the same length as the other foot’s toes. But the foot itself is two sizes wider, and the part the toes are attached to is curved much more steeply.) If your toes don’t fit into the little toe pockets properly, they won’t work for you.
It took me about two hours of walking around in them inside the house to realize they just weren’t going to work. They really fit better, and feel better, than most shoes I’ve tried, and I’m very sad I can’t wear them. My left two smallest toes go numb.
The idea itself is great, and I have hopes the company will figure out a design that works for the irregularly-toed market soon.
See, I thought I had cute little standard sized toes, but apparently my pinky toe on my right foot is a little longer than standard size. But then, I was only going from a size 36 to a size 37. As everyone else said, definitely try it out first, maybe you’ll find out your toes aren’t that freakishly long after all. 
I ran on pavement (suburban streets) which is why striking your heel hurts. It doesn’t hurt at all though, if you’re running on the balls of your feet. The feeling of vibram-clad feet on grass is amazing though. It’s so soft and bouncy.
I do love how the shoes look so amphibian. I bought the shoes for the benefits of barefoot running, but the strange looks are just a bonus.
This has been my experience. It’s like wearing a glove on your foot. Much, much better than flip flops. And they are pretty quick to put on after you’ve done it a while. At first I had trouble getting my pinky toe in, and I’d end up using my hands, but now I can put them on without using my hands at all.
I’ve had mine for almost a year now. I did poke a small hole in one of the big toes from my toenail, but other than that they’ve held up well, and the hole hasn’t gotten any larger.
I got the classic style. I like minimalist styling, but the cord thing does rub into the back of my foot. After a little while I built up a callous, and now I don’t notice it. I might go ahead and cut the string off; it doesn’t really seem necessary to tighten the shoes, as they fit me pretty well. There is a little extra room in the heel for me, but I have that problem will all shoes. It doesn’t affect my comfort level when wearing them, so it’s not a big deal.
I believe the KSOs have a little strap that goes over the foot though, so none of the issues with the classic style would occur. Here is a good review on the fit of the different styles.
The only other thing to be aware of is that they tend to get smelly if you get them wet. I end up washing (machine wash, air dry) mine every week or two. Probably because I use them as everyday shoes. Normally I don’t wear anything else. (I did switch back to tennis shoes for the winter for below freezing temps, and I hated them! Like wearing concrete.)
I don’t really go running; I mostly just walk, but I’ve not had any problems with that. I can walk on concrete, mud, gravel, or rocks, or really anything just fine. If I step on a small pointy rock that I was not expecting my foot automatically corrects itself and doesn’t put my full weight on it. But I suppose when you are running you might not do that. I’m not sure, since I don’t really run often.
And I do get a lot of comments and looks from people. I just tell them the same thing, that I hate shoes, and it feels like being barefoot. If that is sounds like you, you’d probably like them. I would go without shoes if I could get away with it, but there are all those places where shirt & shoes are required, so that’s why I jumped on the vibram bandwagon.
Do these people find looking at feet gross in general? Because I’ve never understood that.
I’ve not gotten any of the “gross” comments. For me, it’s mostly been the verbal version of this thread. I’m shopping for groceries and one or two other customers and the checkout person will come up and ask whether my shoes are comfortable, whether they’re hard to put on, and where I got them.
YOUR SIZE CHART ONLY GOES UP TO 12, AND I’M A 13. CAN I STILL WEAR FIVEFINGERS?
If you look closely at our size chart, you will notice that the numbers printed across the top of the chart refer to your foot’s length in inches, not US size. We found that, due to the precise nature of the FiveFingers fit, the most accurate size translation was in inches, not US shoe size (which varies across brands and styles).
FiveFingers can fit up to a 12 inch foot which roughly translates to a size 15. In order to find the right size, please measure both feet from heel to longest toe with a ruler in inches and refer to our size chart for the right size.
In one case, yes the friend has some pretty wacky “feet issues” but 3-4 other friends just find them “gross” for some reason. I just don’t get it myself but shrug.
On the other side of that coin, I certainly do get a lot of questions from strangers and they do tend to be positive or at the minimum just curious inquiries.
