Okay when I got these shoes they were super duper tight. But I knew a way I could make them much looser.
So first you get a pair of socks, put them on.
Then put on a second pair.
Put your shoes back on. They will be very very tight but that's good. (I look stylish don't I?) 😉
Get your hair dryer.
Turn it on medium high heat.
And blow dry for 20-60 seconds.
Let them sit, just until you don't feel the heat no more.
While your waiting try to move your toes up and down
Take them off.
Take off your socks, and try them on. If there still are tight repeat everything again.
