Nothing to worry about sweetie .. think first those people who can't even afford atleast food for their self .. you won't die having that old stuff in your feet .
I'd recommend any of the following options: 1. Clean your old shoes up as best as you can and wear them. (No one is going to notice that you are wearing last year's shoes anyways so I wouldn't worry.) 2. Get a PT job and buy your own shoes. Instead of relying on your mom for $. 3. Work out a plan with your mom where she will buy you new shoes in exchange for you doing household chores. This will work especially well if you promise to say do half of the chores before you get the shoes and the other half once she's bought them for you. 4. Sell some of your stuff (make sure your mom agrees with this first) on Kijiji or something and then use the money to buy yourself new shoes. If you can't afford to pay full price for them then go to a thrift store, or discount warehouse store and get a used (new to you) pair.
I keep on cleaning and washing it, but it's so useless. Because my shoes have yelloww stains on the side. And my shoes' brand is Everlast.
Just clean those shoes and you are good to go.
