Edwin,

I’m a believer in mixing it up a bit with shoes, so I don’t
necessarily see a problem. Personally though, I have a hard time
avoiding a heel strike in more traditional shoes like the adrenaline,
so everything I run in now has a reduced heel to some degree, but I
rotate regularly. Regarding a 4 week transition, I’d say go by feel.
The Kinvara does have some heel, and if you have been midfoot striking
for awhile you might be ok. If your calves get really sore after your
first few runs in them, I’d take it slower as that indicates that you
need more adaptation. Be smart, listen to your body, and all should be
well.

Good luck!
Pete

Thanks, trying to spread the word, but lots of people still stuck on the old way of doing things.

MT101’s are a reasonable first choice, and should you desire to move to something less the NB Minimus Trail MT10 might be a good next step.

Matt,

Kind of funny, isn’t it. The amazing thing to me thinking back is that I
almost never had any aches or pains when I just picked the shoe that I
thought looked best, and now one of my favorite shoes is a cheap XC flat.

Pete – thanks for the reply, and i’ll listen to my calves… I’ll post a follow up post marathon if all goes well. thanks again!

Now I’m considering rotating between my Adrenalines and a lighter trainer/racer for my workouts and races. I’m still not sold on the whole barefoot running movement but I can see that I should be open to other ideas besides what the 20 year old at the running store told me.

Tuck,

Thanks for the link – I recently read a post on Krupicka’s blog about his
shoe philosophy, which I liked a lot. Hadn’t seen the RT article though.

hi pete, again, thanks for reading my very long comment! and, thanks for the preview link. as a scientist, it was a refreshing read, since it takes into account the adaptive and integrated response of the human body. the article seems based in scientific reality, as opposed to the nebulous, usually unsupported claims made by various running shoe companies. my motto these days is definitely becoming “do what works.” yeah, i might overpronate, but i only want to treat it like a problem if it IS a problem. there must be a reason i got through a lifetime of gymnastics (talk about using your feet!) and plain ol’ walking all around cities without injury, when i never gave a thought to anything beyond comfort. all my reading and exploration of running science is only making me realize that i’m really better off (intellectually, and maybe physically) trying to figure out things for myself and try, like you, to find trustworthy, peer-reviewed literature on the subject. so, i respect your opinions given what i’ve read here so far, but i’ll be sure not to give them too much more weight than, say, i would to a nike salesperson :) i’ll be curious to see what discussion is generated from steve magness’ article, and i’ve bookmarked your blog for future visits!

Thanks! Not really skulls in the technical sense, just bits of cartilage.

Amanda,

I know Brooks reports values for some of their’s, and RW may be more
spotty than I thought – maybe try the RW Competition store – tab on
top if their webpage?

I’ve been running in stability shoes (Brooks Adrenalines) + full orthotics (heel lift/arch support) for over a decade; a few years ago i shifted to mid-foot to lessen the yearly knee and ITBS strains. I’ve been injury free and wanted to take the next step and try a shoe better for mid-strike running.

I am planning on doing my long runs in my Adrenalines and my mid-week (2x) in the Kinvaras — does switching between high and low heel shoes cause issues?

I’ll go by feel as you instructed, but is there a transition period/plan I should try to use? e.g. am I crazy to think I can use them in my next marathon in 4 weeks
