There are many reasons why you'd want to make too small shoes bigger. Maybe you've just bought a new pair of shoes; they haven't been worn in yet, so they're a little tight.
Thankfully, most shoes can easily be stretched out to achieve some toe-wiggling room! And there are a few cheap & cheerful shoe repair hacks that you can easily do at home.
