Vibram Five Fingers KSO Trek Review: Running in My “Bear” Feet

Vibram Five Fingers KSO Trek

I’ve been running in Vibram Five Fingers off and on for three years now and they are not the miracle shoes that some would have you believe. For one thing, you won’t win any fashion awards. My college-age daughter won’t be seen with my in public when I’m wearing my Five Fingers. And for another thing, they may not cure everything that ails you. When I finish running I still feel like I’ve been run over by a bulldozer. My knees still hurt – just not as much or for as long as when I’m wearing regular running shoes.

The bottom line is that after three years of use my Classics are starting to wear out and I liked them well enough to cash in my REI dividend and upgrade to a pair of KSO Treks. Here are my first impressions.

Fit and Sizing

I followed Vibram’s sizing recommendations and got size 45 – the same size as my Classics, which are a little too snug. To be clear about this, the KSOs run a little large and a 45 in Treks are like a 46 in Classics.

Because the footbed of Five Fingers cup the heel and toes, these shoes won’t “give” with use. For hiking and running it’s probably better to opt for a little loose rather than a little tight if you’re between sizes.

First Run: On the Dusty Road

The KSOs have a thicker sole and this makes a huge difference on the gravelly trails where I do most of my running. There’s still a chunk of ouch! when you step the wrong way on a stone, but it’s far sight better than the thin soles of the Classics.

Keeping Stuff Out

On their “maiden” run the KSOs lived up to their name – the high cut, firm closure and kangaroo leather uppers really did Keep Stuff Out. The Classics, with their “ballet style” cut and stretchy fabric always ingested a certain amount of dirt. Running in the sand was a good way to grind holes in your feet in a hurry.

Support

I have flat feet and at times tape my arches. The way the KSOs strap up they seem to give a decent amount of arch support.

This is a first impression. So far I’ve put the KSOs through a few miles of trail and a game of Night Ultimate Frisbee, and so far so good. These lightweight runners give you the “barefoot” experience without the pain and suffering of actually going barefoot. The quality and workmanship are excellent.
