Mechanical devices or stuffing can physically stretch the shoe material overnight or when not being worn.

Shoe Stretchers: Insert adjustable shoe stretchers into the shoes. Turn the handle to expand the stretcher slightly in length and/or width, focusing on tight spots. Leave them in overnight or for a few days.
Stuffing: Tightly pack the shoes with socks, newspaper, or washcloths, ensuring the material pushes outwards in tight areas. Leave them stuffed overnight or longer.

N/A - Provides constant, gentle pressure to stretch the shoes without needing to wear them.
