for training you want something with proper foot placement.
many shoes now have you stepping in a very unnatural way, essentially leading withyour heal.
this happens when the heel is higher, like a LOT of NIKE's.
I went a little extreme learning biomechanics and all that.
I don't like the barefoot shoes or nike free.
I haven't tried the latest ones but puma votaic was great and bought like 4-5 pairs, turin was basically the same but leather. then they changed the construction...
I think the votaic 2-3 and 4 were all good. same with turin but maybe not 4.
all the shoes I love were discontinued! lol!
ill have to see what the adi high tops I like were but no good as they are non existant.
you want things that leave you foot in a natural position, leading with the ball of your foot.
the votaic feel like two plat forms, one for the front/ball the other for heel.

the black ones were the best shoes I ever had! lol
I have seriously 5 pairs of these here with me, and 2 more old ones. bought 7 in total, they are that good.
