Thanks for a great review which helped me make a decision to get a pair of these. Well, having had them for about 4 weeks, I finally got around to running a 10K in them. My first impression was that I much prefer a more heavily cushioned shoe, but after a few k I wasn’t really noticing the sole. I don’t really know whether the fulcrum does anything, but I can say that over my first run I averaged about 15 seconds per K quicker than I normally run. Not exactly scientific, but I intended to run an easy 10k, but ended up pushing myself a bit harder than usual, and I don’t know why. So I guess my experience is similar to yours. Thanks again for a great review.

I’m also skeptical on the science, seems every company has to have a marketing angle with their shoes, and this is the Karhu hook. Not sure if any research on it has been published. Does look like a nice shoe though.

I mean that it just makes no sense from a physical point of view.
What I would see is a study about good old canvas sneakers, like the one generations of runners have worn. These do not hinder your natural foot movement in any way and do not need any fancy marketing snake-oil based on fantasy physics and DIY physiology.

Nice shoes, anyway… I would really like a pair of spikes like the ones God whore (God = Emile Zatopek, of course)

So Karhu tested with 4 different models and 4 different Asics (or was it 4 different brands) and the result published on Karhu technology page is average numbers.

It is the most important that you could feel it was hard to go slower as Fulcrum worked and converted your downward footstep energy into forward momentum.

Great review!:)
