Goal and options: Stretch a spot in snug shoes.
output answer:
Put the new shoes on your feet (chunky socks and all) and blow dry over the tight spot for about 20 to 30 seconds, far enough away that you don't burn your feet. Then, take a quick walk around the room to loosen the shoe material while it's still hot and flexible. When you think they've stretched enough, remove those chunky socks and test them out!
