Wear Test: Vibram FiveFingers® KSO

23 03 2010

As part of my informal Spring 2010 “Beginner’s Mind” running/sitting rejuvenation program, I thought: what could be more beginner’s mind than barefoot running? I decided to try (almost) barefoot running and purchased a pair of Vibram FiveFingers® KSO. I’d been eyeing these for about a year or so, toying with the idea of trying out a pair, and finally decided with the final arrival of Spring that there was no better time to slip them on and go for a run.

Factoring in postage, the KSOs cost almost exactly the same as an average new pair of conventional running shoes, perhaps slightly less. I thought briefly about going for Vibram’s “Hummer” model, the KSO Trek, which are probably better suited for trail running, but they were $40 more – and this was strictly an experiment. I plonked down my money for the KSOs and they arrived in the mail a few days later.

Herding the piggies

Out of the box they had the same potent “new running shoe smell” I was used to, but of course looked entirely different. The rubber sole, which curled up around the front of the toe boxes for additional protection, certainly felt very thin. They looked sort of like high-tech bedroom slippers for circus clowns. Apprehension crept in, with a micro twinge of buyer’s remorse. What sort of consumer karma had I tapped into here?

It took me a few minutes to get all of my piggies herded into their private pens, but they all fit comfortably with the possible exception of my right little toe – for some reason it felt slightly and a little oddly extended, despite additional squirming and flexing to reposition things. Finally I decided enough already — it was going to be one small step for a man, one giant barefoot leap for mankind. I headed for the park.

At the park

I had decided on a very easy 40-45 minute test, running about 30% of the time on concrete and the rest cross-country. The park is a mix of open field, concrete walkways/parking lots, and soccer fields, with some minor rolling terrain. Ground conditions were clear and fairly dry, with some softening from the meltoff of the previous day’s surprise one inch of snow.

And away I went.

Stepping gingerly, I started out on a two-minute walk just to get a feel for the shoe. I could feel the changes in the surface literally from step to step, and my calf muscles were obviously working harder. It really felt like I was walking barefoot. And then I started to run, going for five minutes at a time followed by a one minute walk.

After only ten minutes or so, I had gained full confidence in the shoes and was simply enjoying the run, even daring to go faster than I had intended – probably topping out at around 8:30-9:00 minute mile pace in the middle stages. I ran over a broad covering of pointy-ended acorns without fear, up and down hills, through soft dirt, over concrete. My right little toe, the one that had felt a little out of place before the run, had found the sweet spot in its stall and settled in comfortably for the ride.

What I liked most about the KSOs was how they fully connected me with my run. I realized how, in conventional running shoes, we’re not allowed to make much contact with the actual ground surface. We’re missing a lot. I really enjoyed how I could feel the surface textures constantly changing under my feet, helping to keep my head in the run. The forty minutes passed way too quickly.

And that, to me, is the real magic of the Vibram approach. So much of today’s running technology is designed to take you out of the run – GPS monitors, MP3 players, heavily cushioned shoes. It’s as if we were trying to recreate tooling around in a Cadillac Escalade on foot, ironically seeking ways to escape the very experience of running. Sure, they look a little odd, but Vibram’s technology actually serves to put you more in touch with your running environment and make the experience of running more intimate and real. Put simply, it made me more aware of my running. And anything that helps make me more aware, in my book, is a good thing.

Post-run

I expected soreness in my feet and calves on the next day, but I didn’t have any, so I guess being a little cautious the first time out was the right move. I wondered how the shoe would really hold up — for one run at least, they appear to have held together quite nicely. I’ll be interested to find out how durable they are over the next few months.

For now, this is definitely my go-to shoe for shorter (an hour or less) runs cross-country and on non-technical trail. Beyond that, I don’t know how much braver I’ll get; I’ll just take it one nearly barefoot run at a time. But I’m really looking forward to trying them again — and I’m afraid I’m starting to covet the KSO Trek. Desire is definitely endless.

Wow. I am totally intrigued.

I ran barefoot on the beach for 30 minutes a few weeks ago and hated it…can’t imagine enjoying those wacky shoes. But, I did enjoy your report very much. Thanks.

Thanks for the comments — they’re intriguing, they’re wacky! They’re a little bit of everything, I suppose. But I’m confident 2-3 runs/week in the Vibrams will really be beneficial, especially for my calves and Achilles … and for more aware, involved running in general.

For those wondering how to transition, I would say taking it slow, short, and easy for the first few runs is definitely the way to go. Here’s a good short article on how to make the transition to Vibram-style footwear:

I see you ordered these online. Did you order the same size as your ordinary running shoes? I’ve been running once or twice a week in “minimalist” shoes (Nike Frees) and I Iike the feeling of the ground under my feet. Maybe I’ll give these a whirl.

Mark, the sizing is a bit different, as you’ll see when you check out their sizing chart — you’ll do best to measure your feet as the Vibram website directs. I took a 41, which I think probably translates to around a size 10 1/2; I typically wear a 10 or 10 1/2 in conventional running shoes, depending on the brand and model.

Glad to hear you like them – I think they are game changers. I have actually been transitioning from running in Five Fingers to running totally barefoot. I encourage anyone who is interested in barefoot or minimalist running to thoroughly study this site:

You might find that no shoes are even better than Treks (which look crappy to me – the soles are so thick).

Sophia, I can’t speak for climbing, but it’s definitely a breath of fresh air when you run in them.

After a couple months of use, how have your KSOs held up? Have you bought and tried the KSO Treks? Are the regular KSOs good for trail running (i.e. State Park walk/bike trail)? Or are the KSO Treks really worth the extra $40 if I want to run on trails that have twigs, small branches, small rocks, pot-holes, etc with varying density in sand, grass, etc.

Are regular KSOs good for trail running or should I get the KSO Treks?

Have they held up well over four months of running?

Hi Adam,

The KSOs are holding up great, but bear in mind I only use them once a week for 2-4 hours. But so far, no complaints. I use them mostly on non-technical trail and cross country, and they work great. I don’t know if I would want to wear the KSOs on technical trail, but then I’m more cautious than some.

The Treks — I don’t know. They look a little heavy to me, and perhaps defeat the very purpose these types of shoes were originally designed for. But that’s just me, looking at photos of Treks on the Internet. I have no idea, really.

My advice is to do what I did: get a pair of KSOs and try ‘em out yourself. Your own experience is your best guide.

Enjoy your running!

Really running with Mu: returning to the roots of running « Run With Mu

[...] I think at least part of the current barefoot running trend is based around a nagging feeling of chronic dissatisfaction (what Buddhists call dukkha, or suffering) with the entire high-tech, high-pressure approach to running that’s currently prevalent. Many runners are, whether they realize it or not, hungering for simplicity – even if it means spending yet another $100 on a pair of glorified clown shoes to quickly buy into that simpler feeling, or at least a talisman. And yes, I did it! [...]
