each size shoe grants a different power to its wearer, but while the shoe has to be worn correctly, it doesn't have to fit well, so people with small feet can access more powers than those with large foot. the smaller the shoe the more powerful, for example massive clown shoes just let you make rainbow bubbles, while baby shoes can let their wearer generate a near impenetrable shield. as a result of small shoes being more powerful people generally use young children as their apprentices to fight their battles for them, leading to the totally original series the shoe shop wars, by Brennen Mole.
