You're out on a run. Your nose is getting stuffy, so you lean to the side for a quick farmer's blow. It's cold out, but you didn't realize how cold until you go to wipe your nose with the back of your glove to clear off any additional moisture -- only to find that it's already frozen around the edge of your nostril in mere seconds.
Welcome to the inaugural Asheville Marathon, held on the grounds of the beautiful Biltmore estate. "Well," I thought dramatically at around mile 20, "At least I'll die somewhere majestic."
The review covers the KSO Trek's design (sole attributes and thickness), aesthetic, performance, fit, and more. You can read it by going here.
Updated 9/10/09: See added photos below!
The fivefingers fairy surprised me today with a sneak peak at the brand new Vibram Five Fingers KSO Trek barefoot trail shoes! Here is my unboxing and first look:
Apologies for any video clunkiness (as in, the little section where you can't see my KSO Trek-clad feet and the abrupt ending). 16:9 HD video plus wanting to get this to you guys as soon as possible meant taking the video as it was!
The kangaroo leather is smooth and buttery and looks so fancy I hardly want to get them dirty (though I must!). The leather is quite thin but feels strong. As for breathable-ness, after having worn them for a short walk here in Atlanta (Around 80 degrees Fahrenheit), my feet feel cool and dry. My toes feel very nice and cool, in particular. The sole of my foot against the smooth leather inner is particularly nice.
For a slew of information about the leather used in the KSO Trek, check this info-page from PackerLeather on their K-100 high performance leather. In brief, and there's a tag that came with the KSO Treks that talk about this, the K-100 kangaroo leather is billed as providing extreme strength, perspiration resistance, high water vapour permeability, high color fastness, and has an "microblok" anti-microbial treatment. Regarding water resistance, tag notes that the K-100 "leather dries faster" and has only 28% water uptake after 60 minutes (as compared to 235% water uptake for "non water resistant leather").
Aside from the use of leather, the Trek also employs the standard, thin synthetic material to line the sides (not the top) of the Trek, which I imagine reinforces the leather somewhat at the ankle. Additionally, as some had asked, the sides of each toe slot are the synthetic material.
The aggressively lugged KSO Trek sole maintains flexibility while still looking sufficiently "beefy." One open concern among VFFers regarding the Trek revolved around the added thickness and aggressiveness of the Trek's tread—would it impeded the minimalist design of VFFs? The proof will be in the pudding—that is, extensive field-testing by you guys—based on an initial inspection, the Trek is very flexible, similar to what you already expect across the fivefingers line. Toes can still easily bend, particularly upwards, which is pivotal for functionality. This is even as the toes employ a thick-ridged design.
As for the addition of EVA, on light use if I didn't know it was there, I would assume it wasn't. In other words, I don't notice the EVA. I still feel the variations in the ground outside. Interestingly, what I don't feel through the sole is the variations of the Trek tread, itself. I've no idea how they pulled off this feat of VFF design, but it works.
Overall, my initial impression is that the ">KSO Trek will make a strong addition to the Vibram fivefingers line-up as a rugged barefoot alternative for trail running or hiking! And I can't wait to take them out for a spin in a nearby natural park! Even still, dressed in silky smooth kangaroo leather, they are the fanciest looking VFFs yet, so no doubt plenty of people will want to use them for dressier occasions.
The above photos were sent in from a (well-named) new VFFer named Justin.
Here are some pics from a 10 mile hike I did on the Fiery Gizzard Trail (South Cumberland State Park) in Monteagle, Tennessee back on August 15th.
I had just received my Five Finger Sprints the day before in the mail, so this was my first adventure in them :)
Absolutely loved it!
They definitely came in handy when we were jumping off waterfalls and had to climb back up.
Some of the rocks and roots along the trail weren't too friendly, but it was worth it!
Not only was Justin jumping off waterfalls in his VFF Sprints, he also was "jumping right in" to the VFF lifestyle — a 10 mile hike after just receiving your fivefingers could really put your not-yet-adapted feet to the test! Glad you are already getting such great use out of your new Sprints (and I hope you didn't have too much soreness after your VFF trial-by-fire)!
The Vibram FiveFingers shoes are ingenious, well built and a phenomenal personal ergonomic enhancement. They improve your body mechanics at the starting point, your feet. And everything benefits because of that.
Balance, agility and body control are all enhanced. Your hips and spine have better alignment and your heel strike (a major cause of back pain) is better.
"Barefoot Ted" McDonald recently ran the Leadville 100, an ultramarathon race held out in Leadville, Colorado (You might have read about this race in Born to Run).
And since Ted is effectively both the patron saint of barefooting and Vibram fivefingers, he ran the Leadville 100 in the new Vibram fivefinger KSO Treks (You can see them in the above photo from the race!).
I asked "BFT" if I could share with birthdayshoes.com a bit from his account of the race and he kindly obliged. So below, you'll find a snippet from his post for your reading pleasure. For the rest, you'll have to head over to barefootted.com:
What an amazing experience...running 100 miles in 25 hours and 54 minutes up in the Colorado Rockies in the town of Leadville, Colorado, 10,000 feet above sea level.
From my point of view, this year's race was blessed from the beginning...sporting my new Vibram FiveFinger KSO Treks...and some sponsorship money to pay for the race and some travel...thank you Vibram...I was also blessed with a fantastic crew and pacers...a luxury I did not have last year...made all the difference being part of a team! Thanks! ...
[Later, describing a section of the race ...]
Got into Twin Lakes inbound feeling ready to run 40 more miles. Picked up my pacer Scott who was sporting red VFF Sprints...and off we went. Just before we took off, I downed a Chili Chocolate Mocha from Proven Grounds in Leadville...it was delicious...but it didn't mix well with the other stuff I crammed down my throat, so Scott's first taste of ultra nastiness was me upchucking the coffee just after climbing out of Twin Peaks. Vomiting while walking-running is a ultramarathon skill. Scott was a bit taken aback, but we soon got in stride making our way to the finish.
Scott ended up staying with me all the way to Powerline...25 plus miles on his first pacing adventure. What an amazing job. Excellent company the whole way. ...
It must be quite a feeling to run for a solid 25+ hours — 100 miles. Congratulations on your finish, Ted!
Additionally, I wanted to pass on a post Ted made to his barefooting/minimalist footwear Google group about how to run barefoot:
So, you wanna start running barefoot or minimally? Before you do,
realize you are most likely in the process of rehabilitating
yourself...either from little or no movement or from a running style
that is significantly different from what you will experience starting
My basic points are to start slowly...avoid over-exuberance!
The 3 main things I emphasize in my coaching workshops are:
Gentle ball-heel-ball landings - feet and arms moving in same
Quick cadence - leg speed
Stable upright posture and engaged core...no bending at waist.
You can use this same style to practice at a walking pace too.
Barefooting itself is all about mindfulness and presence. Running
like a Monkey, not like a Robot. Aware of your body and your
environment AT ALL TIMES. Listen to your body...learn to hear what it
is telling you. Adjust accordingly. Advance accordingly.
Edgar ("dardo" on the forums) recently picked up some black Vibram fivefinger KSOs and has been wearing them to work — giving Segway tours of Barcelona!
I asked Edgar how VFFs worked with the Segway and also what kind of reactions he was getting from his fellow Barcelonians. Here's what he had to say:
The shoes did affect my segway driving, I used to have a comfort mat on my segway, a padded platform so your feet do not hurt. After using the segway for a few days I took the comfort mat out, it is uncomfortable now and I no longer need [it] :)
As for people seeing my shoes, most of the time they do not see them due to the segway, which is fairly spectacular on it's own. Also Spanish people are not that open and most of the times will look but not ask. Most of my customers do ask about them and surprisingly to me a few of them knew about them and the father of one american lady had a pair of VFFs.
On a personal note I have been wearing my KSOs for about 3 weeks non stop now. I feel my feet stronger now and the soles are also much more resistant. Last week I did a half hour run at a nearby park and I felt lighter than last time I had been running (about 4 years ago due to knee pains), also less tired and no pains during the running session nor next days. I am quite excited because I believe I will be able to run again, and only with the VFFs of course!
A Spanish newspaper (El Periodico - pdf) also interviewed Edgar about his tours, and in the photo they published, similar to the one above, Edgar is sporting his VFFs.
Brett will be running the race in his Vibram fivefinger Classics, which are prominently featured in the promotional video the library shot for the race (below). The video is done in a silent film style — Brett is shown running through town (VFFed!) in order to help a guy caught beneath a tree branch return a book. Along the way, Brett saves a few teens from reckless behavior by giving them good books to read!
By the way, the race has an interesting catch — all runners who "Beat the Director" will be given back $10 of their $25 registration fee (all proceeds from the race go to setting up a teen area in the Library).
