joking apart, have you thought about special trainers, I used to suffer from knee trouble when i first started running. I was overpronating, so now I train and sometimes race in them big trainers, the Mrs says I look abit like scary spice (without the hair) but they sorted me out eh.
now back to joking:
u wanna.. u wanna... u wanna.... jig a jig ji!
Soz couldnt resist.
