I'm still trying to analyse why I liked it so much! I'll put down some thoughts, but before then, a few links with background: Wikipedia has a good entry on barefoot running with enough links to get going if you are interested. I was running in a pair of these (so, really, I was doing "minimal" running rather than proper barefoot).
I heard about barefoot about two years ago on some blog. While reading, I tried sprinting up and down the hall both barefoot and with trainers. I instantly noticed an enormous difference (give it a go, see if you do too).
The reason I decided to try barefoot now was that a few runs back I had some knee pain. I've bought in to the barefoot thesis: it makes a lot of sense that out bodies will work best running in the way they're evolved to run, and my personal testing two years back had convinced me that running in shoes moved me very far away from my "natural" evolved style.
I've done a tiny bit of due diligence on going barefoot (I should definitely read up more). They reckon that you should take it easy when you start with barefoot, so I looked for an iPhone App that would help me work through a few short intervals and found this great one called… oh, you know that bit already?! Okay – I dialled in week two on Get Running and off I went!
Before I started, there were a couple of things I was concerned about:
I thought it might hurt a bit.
It didn't.
I think the VFFs are perhaps still quite padded really, but it really didn't hurt at all, ever.
What ever surface I ran on was a delicious and wonderful learning experience


Stones and gravel are great: you know it should hurt: running barefoot on to a small sharp rock, but it doesn't. I found myself thinking "take that, stone! Ha! I'm invincible!"
On mud, while the shoes definitely slip about, I felt far more sure footed than I ever have in regular shoes. I noticed I was happy making aggressively sharp turns I'd usually keep gingerly wide on. If you've ever had a bike with breaks tuned up really sweetly so that you can easily skid about, it's a bit like that – I just can't stop myself messing about.
Rocks, tree roots and pot holes become a playground – something fun to interact with. I had to hold myself back from launching at park benches and running along them, or trying to run up and jump off tree trunks. Perhaps next time… (I think the biggest danger in these shoes is I'll forget I'm 35 and only remember half way through trying to run up a tree trunk & summersault that I've no idea how to actually do that).
I thought my feet would be cold.
They weren't. Not even a little bit.
It's warmed up a lot here, but it's still only about 10ºC. During the run I noticed that my feet were toasty warm, which was extremely unexpected. I don't have an explanation at all, but there was definitely no coldness. Great!
What else did I notice in the run?
I found it really hard to stop myself actually running and sprinting, rather than jogging at my usual pedestrian pace. This might be because I'm used to running continuously, or in relatively long intervals, but the whole experience was so fun, it was hard not to break out in to a dash.
I felt a little bit conspicuous at one point. Like – that guy in Arrested Development who rides on a Segway. But the only time I noticed it felt funny and good, so that was okay.
How about now.
Well, my knee feels a little bit achey. Oops. The pain I had before (that made me try this out) was a really nasty sharp pain. This is just a dull pain that feels more like "oooh, I'm not used to that, can I have a bath please?" instead of "Hell no, you can stop that right now!". I think I'll read up a bit more on the web and see if I can find some advice on running style before my next try. I'm definitely going to keep trying this though, because it's too enjoyable

Bottom Line
I'm not sure if this is for everyone, and I'm not quite ready to get evangelical yet and rename "Get Running" to "Get Bare" or something, but I definitely had a blast, and I'll keep doing this exclusively when I run for now. If you want a no investment way to try barefoot, wait until it's warm in your neck of the woods, then go out for a bit of running on some soft but fairly short grass that you can be pretty sure isn't hiding broken glass, etc.
If you've got any questions or thoughts, jot down a comment and I'll do my best to respond.
Happy running,
