Running

you should be able to answer me future doctor.

it is technically inversion/eversion isnt it?

overpronation is marketing bullshit.

aye.
Over pronation- literally means your foot moves to far, very aspecific.
My 2p- get yourself looked at by someone who knows what they're doing- just as you would with expensive bike stuff, but this is much more important in running as you can really fuck yourself up, like my knee is, yay!
