KSO Men's

The KSO is arguably our most successful FiveFinger to date, mainly due to its versatility. We added this back into the mix a few years back to celebrate the rebirth of a legend. When you're scrambling up a rocky bluff or bounding along a riverbank, the last thing you want is gravel and grit seeping into your FiveFingers. So why not Keep Stuff Out! The KSO has a snug fit, one of our most minimal sole constructions for maximum ground feel, and a breathable, quick drying upper. The KSO also features a thin, abrasion resistant stretch polyamide and breathable stretch mesh that wraps your entire foot to do just that. A single hook-and-loop closure helps secure the fit. Non-Marking XS Trek performance rubber soles are razor-siped for sure grip.

    5.0 out of 5 stars THEY ARE AMAZING (and there is a way to clean them)
    Reviewed in the United States on November 23, 2010
    Size: 10.5-11Color: Black/Black,Verified Purchase
    When I first got these, I wasn't too sure if I was going to become an instant fan. I've always been used to shoes. After wearing these for a few days, I came to realize I didn't want to put anything else on my feet. Now, there is only one problem with these... If you wear them all the time like I do, they start to smell. It took me awhile to find something to clean them, but I finally came up with the solution. On amazon they sell a multi-purpose cleaner called Odoban. This stuff will kill any bacteria growing on your vibrams, without causing skin sensitivity. (at least for me) I bought a small shoe-box sized container and put the Odoban solution in there. Whenever I need my Vibrams cleaned, I soak them in that small container then rinse them. That's all there is to it.

    If you are planning on running in them, make sure you have a good running style. If you tend to hit the ground hard, work on your form before buying these. They don't have support, which is no big deal if you have good form and stay off solid surfaces. If you don't have good form, you could get injured from lack of support. Also, try to stay off pavement with these. It's just better for you anyways whether you wear shoes or Vibrams.

    This product really is beyond being just a fad. If you are buying them for style, you might take or leave them. If you are buying them for their functionality, then these are for you. I remember running around the yard bare-foot when I was a kid. These accomplish this wherever you go.

    Last note: MAKE SURE YOU GET AN ACCURATE FOOT MEASURE. I was very careful about measuring my foot size before purchasing these. They are not at all like shoes where you can be within a size or so and still fit fine in them. You have to be precise with your sizing. These shoes fit around your foot perfectly to help your foot work the way it was naturally designed to.

    5.0 out of 5 stars Intelligent Design!
    Reviewed in the United States on September 23, 2010
    Verified Purchase
    For all my pedestrian life, shoe manufacturers have been working on the assumption that the human foot is a faulty design. Shoe-engineering has always clamored for More Support, More Support, making the "platform" stiffer and the heel wider, and always vacillating between heavier construction but lighter materials. Podiatrists have made comfortable fortunes by prescribing uncomfortable arch supports, and more and more people have found themselves lifetime committed to wearing orthotics.

    Vibram Five Toe shoes are based on the assumption that "evolution got it right", that the human foot does its job quite well if it is allowed to flex and grip as it is 'built' to do. The toes are fitted independently, like fingers in gloves, and the sole is merely a tough membrane like the calluses that form naturally on the feet of barefoot peasants around the world. The construction is as light as a hiking sock or a moccasin. The shoes are intended, I suppose, to be worn without socks, but I prefer to wear the lightest Injinji five-toe socks in them. It was the Injinji socks that I wore inside my stiff heavy old hiking boots, on a 20-mile hike, that persuaded me to try these Vibrams. No hot spots, no toenail problems, and my "dogs" weren't barking at the end of the day.

    Personally, I confess that I've been more concerned all my life with the durability of my running and hiking shoes than with the durability of my feet. In my sixties, that 'concern' has proven to be misplaced. My sturdiest Vasques boots are still in good shape but my feet have been showing signs of wear and tear. So, I thought, why not try the Vibram shoes, since the Injinji socks seem worthwhile? Besides, if they don't work for walking and running, surely they'll make excellent kayak/beach shoes.

    Putting the five-toe shoes on for the first time isn't an encouraging experience. They don't 'fit' until they've been worn to the shape of YOUR feet. They're tricky to get over your toes properly for the first six or eight times, and it's hard to believe the your heels will enjoy the pounding on cement sidewalks or rocky trails. I've been wearing my first pair for all outdoor activities now for about two weeks, and I love them! Light, cool, free-feeling, and I don't seem to be having any problem with jarring on hard pavements. They look somewhat funky with a tuxedo, I have to acknowledge, and on the street people will gawk at your pedal extremities rather than your ample forehead or bosom. Hey, that's not such a bad thing in itself!

    I can't yet declare that my overall 'foot health' will permanently improve from wearing Vibrams. Also, I doubt that they will survive as long as a pair of indestructible Vasques; the soles are thin by design and will wear through. But the price isn't so high, even if you replace them twice a year, in comparison to the potential benefits of accepting the wisdom of Evolution and letting your feet do the job they did for your genetic ancestors over the past four million years or so.

    4.0 out of 5 stars Great, but it doesn't quite fit
    Reviewed in the United States on April 5, 2013
    Size: 8.5 - 9Color: Black/Black,Verified Purchase
    I've been having foot pains all over, top and bottom, ever since moving to New York City and starting to walk everywhere. The first thing I tried was adding gel insoles to my existing shoes, which actually made the pain worse. Got a new pair of regular shoes too, but it had the same problems. Finally tried the Vibrams, and the pains are gone! I'm definitely going to look into replacing more of my shoes with barefoot-style shoes.

    My feet aren't quite properly shaped to fit into this shoe, however. While the overall size is correct, my big toes fit snugly but my pinky toes barely go into their pockets at all. This is really just a minor annoyance, though, and doesn't stop the shoes from doing what they're supposed to.

    Comfort is okay without Injinji socks, but adding the socks makes it work a lot better. Without the socks, the upper cover and its outline leave marks, but everything is fine and comfortable with the Injinji socks on.

    These shoes draw a lot of attention (even in plain black), and also force a bit of a goofy walk, as you really shouldn't heel-strike but it looks a little funny when you don't. The goofiness of the walk just begs for a run or a jog instead. It's a shoe that makes you want to run or jog everywhere instead of walk.

    I received the shoes much before the due date with a small extra gift which made me happy. The shoes are really comfortable . However their size calculation is not very accurate and I am happy that after going through other reviews I ordered a size bigger than what their calculator was telling me and it fitted perfectly like a sock.

    Le avevo già comprate tanti anni fa durante un viaggio negli USA, in Italia ancora non erano arrivate e ho avuto modo di provarle in negozio con il commesso che mi ha seguito nella scelta.
    Come taglia di scarpe io porto un 40, ma con queste devo prendere il 41. Mi vanno leggermente lunghe su alcune dita, ma i millimetri in eccesso vengono compensati quando indosso il calzino.
    Le uso per allenarmi nei circuiti a corpo libero, per fare slackline e balance board e devo dire che mi danno un'ottima sensazione, sembra di essere a piedi nudi, e mi consentono di avere un ottima sensibilità, ma con il vantaggio che il piede rimane coperto e protetto da eventuali tagli/abrasioni.

    5.0 out of 5 stars Die bessere Art zu laufen !
    Reviewed in Germany on November 10, 2013
    Size: 9.5-10Color: Black/Black,Verified Purchase
    WICHTIG : Die 5Fingers fallen sehr groß aus bzw die Größentabelle auf der Vibram Homepage müssen dringend beachtet werden !!! Ich habe Gröoße 45 und habe mir die 5Fingers in Größe 43 bestellt und erst dann passen diese !!! 2 NUMMERN DIFFERENZ !!!!

    Anziehen ?!
    Eigentlicht kein Problem (wie oft beschrieben). Einfach jeden Zeh einzeln (von groß nach klein) in die Taschen buchsieren und fertig ;-) Wenn man aber eine höhere Kontrolle über seine einzelnen Zehen hat und sie spreizen kann, ist es auch möglich den Schuh OHNE jegliches fummeln anzuziehen ;-)

    Steine/Glas:
    Die Sohle ist angemessen dick, feinere Steinchen (Kies) spürt man fast nicht und große Steine/Kanten sind zwar spürbar, aber tuen nicht weh ! Durch Scherben (zerbrochene Flasche) laufen kein Problem !
    Trotz dieser Sohle hat man ein ausgezeichnetes Feedback über die Gelenkstellung des Fußes und kann somit viel schneller auf unebenheiten reagieren!

    Flexibilität:
    Trotz der Sohle enorm flexibel, passt sich sehr genau dem Fuß an und rutscht nicht.

    Als Umsteiger zu einem Barfußschuh unbedingt beachten:
    Erst mal nur eine SEHR SEHR kleine Runde laufen, denn durch die "normalen" Schuhe sind unsere Waden nicht an diese Belastung gewöhnt und durch eigene Erfahrung kann ich sagen, dass man schon mal eine Woche lang (!) Muskelkarter haben kann (wenn man es natürlich sehr übertreibt ;) )
    Der Laufstil sollte auch umgestellt werden : Erst auf dem Vorderfuß auftreten, dann mit dem ganzen Fuß und abdrücken wieder mit dem Vorderfuß ! Dies ist ungewöhnlich, aber meiner Meinung nach (nach gewisser Trainingszeit) viel "flüssiger" und ökonomischer !!!

    Ich selber benutze diese Schuhe neben dem Laufen auch zum Parkour. Die Rückmeldung des Fußes ist enorm! Man merkt viel schneller wann der Boden erreicht ist oder ob die Füße bei einer Landung seitlich gekippt sind und am aller wichtigsten: Was genau unter dem Fuß ist, ob die Oberfläche geneigt ist und ich somit meine Kraft anpassen muss oder meinen Körper doch mehr in die andere Richtung neigen muss. Das alles ist bei normalen stark gedämpften Schuhen nicht so schnell und in dem Umfang möglich ! Dadurch kann man die Landung viel besser steuern/abfedern und belastet nicht unnötig seine Gelenke!

    Für den Alltag ?
    Sehr zu empfehlen ,vorausgesetzt man ist nicht Schüchtern und hat kein Problem damit aufzufallen ;-)
    Die Füße ermüden nicht so schnell und somit sind längere Shopping-trips möglich.
