Perfect fit, and very comfortable for light use.
They are very comfortable and they actually straightened out his toes which is a miracle.
I grew up in Florida, and the shoes free lifestyle was all I knew until I was forced to got to school.

    By A. Khan on June 29, 2009
    Size: 46 M EUColor: Grey/Palm/Clay
    I have always liked to run but as a middle-aged, overweight, back-pain-suffering man, I have had way too many injuries to ever get into serious running. Every time I increased my distance or started running faster, my feet came back to bite me. I have had ankle issues, plantar fasciitis and other heel related injuries causing me to move to more and more cushioned shoes with customized orthotics. But none of these helped and things kept on getting worse and worse. So much so that I seriously thought about giving up running altogether. Came a day, recently, when was 40 lbs overweight and my left knee had started to hurt. Along with that my blood pressure had gotten worse and my back pains had returned (thanks to herniated discs of a few years ago).

    It was only about 6 weeks ago that I heard about Chris McDougall's book, 'Born to Run'. Reading the book exposed me to barefoot running and these wonderful VFFs. I did some Internet research and since I had nothing to lose, I decided to give them a try. I must say, that from the very first time I put these on, I fell in love with them. I wore them on and off for a couple of days in the beginning and the more I wore them, the more I liked them. Then, after a week of trying them on and walking with them in my neighborhood park, I went for my first run and my feet along with all the unused muscles in my calf ached like hell. This went on for about a week. What I did notice right away, though, was that my running form improved dramatically. I was no longer pounding the pavement (or asphalt since that is surface where I run) and my stride was much, much shorter. Also, even though I had aches in my feet and legs, nothing really hurt. The sharp pains in the knees, in the soles of my feet and the heel were nowhere to be found.

    I bought these shoes for my wife and I for running and other outdoor activities because I naturally run up on my forefoot and I hate wearing shoes with all the extra padding that only adds bulk. We have had them for several months now and I no longer get shin splints when I run and find that I like walking around barefoot (real barefoot) much more now. Go easy when you start running in them though as you will get very sore because you will use many new muscles. Your calves will get especially sore but they will also look much sexier after you spend a few months running in these "shoes."

    When I first bought these shoes, I loved them. I wore the KSO, and gradually built up to daily use, including a twice a week 4 mile run. The other days of the week, I ran in regular shoes and increased my speed or distance to accommodate. The KSOs were fun! They made simply walking to the store feel like I was playing. Yep,I felt like a barefoot kid again. Then I bought the KSO treks. I wore them for about a week and then I went on a short hike in them. I often hike all day in regular shoes, but in these, I walked for 45 minutes on a fairly easy Colorado trail. I loved the feel of them when hiking. I could use my toes to grab onto rocks and in softer terrain (like sand and mud) and I could ford streams without worry. But a few days later, I started to develop back and knee pain. I was certain it could not be the shoes. I alternated, as usual, but kept wearing them. At this point, I have been out of commission for two weeks with debilitating back pain. Podiatrist diagnosis? Bad shoes. Or rather, shoes not meant for my particular body. The doctor recommended that, if I wanted to wear these shoes, I should wear them only for Yoga and walking on a flat trail--not running, not hiking.

    I have no doubt that some people can wear these shoes without worry. But I--a competitive athlete from the age of 10--can't. At least, not for running and hiking. My guess is, there are others out there like me. So I'd say--enjoy the shoes, but wear them with caution. If you can get a video treadmill analysis of your stride in the shoes beforehand, that would be ideal.

    There is the argument that my stride has been "damaged" by years of shoe wear and running in high-heeled Nikes and the like. These folks argue that 5fingers will correct that stride.

    I haven't used my KSOs for running so much, but they've made great everyday shoes. Very comfortable! I won't go into detail about what makes these shoes great, though, as there are plenty of other reviews for that.

    I'd just like to offer some advice for those who don't have the option of trying them on in person, and so must try to figure out the right size to order online. I really wanted to try these on in a store before buying, but every place nearby that had them was sold out of the sizes the sizing instructions suggested would fit me best. I ended up ordering three pairs online before finding a good fit, so I'll be glad if I can save anyone else the hassle I had to deal with.

    First of all, when you go by the measuring instructions of using a ruler and your feet against a wall, make sure to stretch your toes out as far as you can, while still keeping your heel touching the wall, before taking the measurement. The first mistake I made was taking the measurement of my toes in a relaxed rather than stretched out position, leading to an inaccurate measurement.

    As the official measuring instructions suggest, you'll want to go by the measurement of the longest toe on the biggest foot(if one of your feet is a bit bigger than the other). But be warned that the sizing typically runs small. Based on the sizing chart, a size 40 should have fit me perfectly, but I found it to be too small. I was worried that a size 41 would be too big, but once I tried it on I was afraid that it also felt too small. I stuck with 41, though, and after a little breaking in I've found it to actually be the perfect fit for me.
