I got a job. After two days of military training, my shoes are wet and smelly at the end of the day. What if I wear it tomorrow? I have no other shoes.

Don't wear it when it's wet. Tell the instructor. After the shoes are dried, spray some air freshener into them. Wash your feet more, and a pair of socks must be changed every day. After drying your feet, you'd better apply some ointment. Especially around the toes and toes to prevent beriberi. If your feet start to itch, stink or blister (you can't help itching if you feel itchy), if so, it may be athlete's foot caused by damp fungi. This disease is more troublesome. (Ahem, sorry, digression. You can talk to the instructor about the situation, but the last thing is to get up early tomorrow morning to buy shoes. This is the best way. Because after all, the money for a pair of shoes is cheaper than the money for treating beriberi, because I am also a beriberi victim = =
