    These are great beach/water shoes.

    Go easy when you start running in them though as you will get very sore because you will use many new muscles.

    I use these shoes running, working out, walking around, and even swimming.

    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 have to admit the first time I saw my old roommate with these shoes that he'd gone and lost his mind, but curiosity got the better of me and several months later I bought my own pair. Since purchasing my Five Fingers I have done everything from swimming to yoga, to weight training to running and true to their word my legs and lower back have gotten stronger and my posture has improved! I highly recommend these shoes to anyone who lives an active lifestyle with a variety of interests. As a single man they also make a great conversation starter at the beach!

    I have been researching barefoot running for awhile and recently read the book Born to Run. I purchased the VFF and I am very pleased with them. Prior to these shoes I have purchased almost every brand of shoe and inserts as well. I have always had arch and knee issues. Since I have started running in the VFF my knee issues are GONE! No arch issues as well. I wish I had discovered these earlier. It would have saved me so much money and pain as well.
