What an unpleasant smell these socks and shoes have (7)

Description: Because i was wearing shoes for so long my feet got a very unpleasant smell and i spent more than 3 days wearing the same shoes and the same socks to go to training and today when i came home from training and i sat down to take off my shoes to let my feet rest i noticed this smell like old cheese or vinegar that comes from my feet and socks and the truth is i couldn't stand having this smell on my wonderful feet
