Yes, you can use an oven or a dryer to help stretch or make shoes slightly bigger, but it's important to proceed with caution and be aware of potential risks. This method is commonly used for leather shoes, but it may also work for certain synthetic materials. However, it's not suitable for all types of shoes, especially those with non-removable or heat-sensitive components.
Here's a general guideline for using an oven or dryer to stretch shoes:
Preheat: Preheat your oven to a low temperature, around 175-200 degrees Fahrenheit (80-95 degrees Celsius). Alternatively, you can use a hairdryer on a low setting.
Prepare the shoes: Slightly dampen the shoes' exterior, focusing on the areas you want to stretch. Use a spray bottle or a damp cloth, but avoid soaking the shoes.
Stuff the shoes: Fill the shoes with dampened socks, rags, or shoe stretchers designed for this purpose. The idea is to create gentle pressure from the inside to expand the shoes.
Oven method: Place the shoes on a baking sheet or aluminum foil and put them in the preheated oven for about 5 to 10 minutes. Keep a close eye on them to avoid overheating or causing damage. The goal is to soften the material, not to cook it.
Hairdryer method: If you're using a hairdryer, direct the warm air on the dampened areas while gently flexing the shoes with your hands. This method may take a bit longer than the oven method.
Test the fit: After heating, put the shoes on with socks or while wearing thick socks to prevent burns. Walk around in them for a few minutes to let the shoes mold to your feet. Be cautious not to overstretch, as it could damage the shoes.
Cooling down: Allow the shoes to cool and dry naturally while still stretched. You can leave the socks or shoe stretchers in place until the shoes are completely dry.
Keep in mind that this method might not drastically increase the shoe size, and it's not a guaranteed solution for ill-fitting shoes. Stretching shoes too much or using this method on unsuitable materials may lead to permanent damage or deformation. If the shoes are too tight or uncomfortable, it's best to consider professional stretching services or invest in a new pair that fits properly.
