Yeah, thats what I thought. I was planning on using them say once a week, just to improve running form, and improve the muscles in my feet which are not trained as much when running in regular shoes.
I suppose I was hoping that by training occasionally in nike free trainers, it might improve my technique, not matter what shoe i was wearing, which would then reduce injuries etc.
I imagine once your feet had got used to them, running times would decrease dramitcally coz they really do feel like you dont have anything on your feet! Sounds awesome to me in that respect,
