To stretch tight shoes for a better fit, try wearing thick socks and walking in the shoes to loosen them up. Alternatively, use shoe stretchers that are placed inside the shoes and adjusted to widen or lengthen the shoes. The DIY method is to fill a plastic bag with water, seal it, and place it inside the shoe. Repair shoes at night; When water turns into ice, it expands and makes the shoes wider. Another option is to use heat from a hair dryer while wearing thick socks inside the shoes, which will ensure they fit snugly.
