Plastic shoes are known to run small, and while they can be stretched, they can't be stretched very much without risking damage to the shoe. One way to stretch them is to use a wooden shoe stretcher, which can be hand-cranked to the appropriate tension. Another method is to put on thick socks, use a hairdryer to heat the shoe, and then walk around in the shoe until it cools. This process can be repeated until the desired fit is achieved, but it's important to avoid using excessive heat to prevent the plastic from warping. A third option is to freeze the shoes overnight to allow the water inside to turn to ice, which will expand and stretch the shoes.

Stretch plastic shoes with a hairdryer
Plastic shoes can be difficult to stretch and run the risk of being ruined with tears or holes if stretched too much. However, there are a few methods to try and stretch them at home. One such method is to use a hairdryer.
First, put on a pair of thick socks or a few layers of socks. Then, put on the plastic shoes. Set your hairdryer to its hottest setting and hold it a few inches away from the areas of the shoe that feel tight. Blast those areas with hot air in 20-30 second intervals. Be sure to wiggle your feet and toes to help the plastic expand. For shoes with zippers, work the zipper up as you heat the shoe.
Once you have heated the shoe, walk around in it until it cools down. This will help the shoe to stretch more. If the shoes still feel tight, put the socks back on and continue to blow dry and stretch. Work the shoe with heat and your foot until it fits exactly how you want.
If you don't want to use a hairdryer, you can try freezing your shoes overnight. Allow water to get inside the shoes and freeze. As the water freezes, the ice will expand and stretch your shoes. The next morning, allow your shoes to thaw for 20-30 minutes and then try them on. If they haven't stretched enough, you can repeat the process.

Wear thick socks with plastic shoes
Plastic shoes can be difficult to stretch due to the material's ability to hold its shape. However, if you are willing to take the risk of stretching them, there are a few methods you can try, including the use of thick socks.
Wearing thick socks with your plastic shoes is a simple and effective way to stretch them. Put on a thick pair of socks, slide your feet into the shoes, and walk around at home until your feet start to hurt. Repeat this process for a few days, and you will notice a significant difference in how your feet feel in the shoes. The shape of your feet and the pressure exerted while walking, enhanced by the thick socks, will help stretch the shoes. This method is especially useful if you plan to wear thicker socks with your shoes, as it is easy to forget to buy a larger size to accommodate for this.
To accelerate the stretching process, you can combine the thick socks method with other techniques. One way is to use a blow dryer on its hottest setting, holding it a few inches away from the shoe and focusing on the tight areas. Wiggle your toes and move your foot to allow the plastic to expand. For shoes with zippers, work the zipper up as you heat the shoe. After heating, walk around in the shoes until they cool down, allowing them to stretch further.
Another method to try alongside wearing thick socks is freezing your shoes overnight. Fill a plastic bag with water, place it inside your shoes, and put them in the freezer. As the water freezes, it will expand and stretch your shoes. The next morning, remove the shoes from the freezer and let them thaw for 20-30 minutes before trying them on to test the fit. Repeat the freezing process if needed.
While these methods can be effective, it is important to note that overstretching plastic shoes can lead to tears or holes. If you are unsure about attempting these techniques, consider taking your shoes to a professional cobbler or shoe repair shop for adjustments.

Freeze plastic shoes to stretch them
While it is possible to stretch plastic shoes, it is not recommended as they can only be stretched a little and are at risk of being ruined with tears or holes. If you are willing to take the risk, there are a few methods you can try.
One method is to freeze your shoes overnight. First, fill a sandwich bag halfway with water and place it inside the shoe. Put the shoe in the freezer and allow the water to turn into ice. As the water freezes, the ice will expand and stretch your shoes. To protect the outer sides of your shoes (and the rest of your freezer items), you can put your shoes in another plastic bag before putting them in the freezer. The following morning, allow your shoes and the bags to thaw for 20-30 minutes before removing the bags. Try on your shoes to see if they have stretched enough. If not, you can repeat the freezing process.
Another method is to use a blow dryer. Put on thick socks, then put on the shoes. Set your blow dryer to the hottest setting and hold it a few inches away from the tight-fitting areas of your shoes. Blast those areas with hot air in 20-30-second intervals. Be sure to wiggle your feet and toes to help the plastic expand. Then, while the shoes are still hot from the blow dryer, walk around in them to help them stretch out more.
You can also try using a wooden shoe stretcher and hand-cranking it to the appropriate tension to stretch them. If this is too difficult, you can always take your shoes to a local shoe repair or cobbler to have them professionally stretched.

Use a wooden shoe stretcher
Stretching plastic shoes can be a challenging task, but it's not impossible. One effective method is to use a wooden shoe stretcher, which can help you achieve the desired fit without causing damage. Here's a detailed guide on how to use a wooden shoe stretcher to stretch your plastic shoes:
Purchase a Wooden Shoe Stretcher:
Begin by investing in a high-quality wooden shoe stretcher. Look for one that is durable and can withstand the pressure of stretching your shoes. Avoid cheap plastic stretchers, as they may not provide the necessary strength and could break.
Prepare Your Shoes:
Before using the wooden shoe stretcher, it's essential to prepare your plastic shoes for the stretching process. Start by cleaning the shoes to ensure there is no dirt or debris inside. Additionally, you can apply a shoe stretching spray, which can help relax the plastic fibres and make them more pliable.
Insert the Wooden Shoe Stretcher:
Now, it's time to insert the wooden shoe stretcher into your plastic shoes. Close the stretcher by turning the metal "T" handle counterclockwise to close the Toe Block. Then, spin the Lengthening Drum clockwise to push the Heel Block against the Toe Block. This adjustment ensures a snug fit inside your shoe. If you need to target a specific tight area, you can insert a Bunion Plug into the stretcher to match the problem area on your shoe.
Position the Stretcher Inside the Shoe:
Carefully insert the toe block of the stretcher into the toe box of your plastic shoe. Push it firmly to the front so that you can feel it through the shoe material. While pushing the stretcher towards the laces, swivel the Heel Block down into the shoe. Ensure that the stretcher is securely in place and fits tightly against the toe box.
Crank the Stretcher to Apply Tension:
Once the wooden shoe stretcher is in position, it's time to apply tension to stretch the shoes. Hand-crank the stretcher's handle to the appropriate tension. Be careful not to over-stretch, as plastic shoes can tear if stretched too much. Stop cranking when you feel sufficient resistance, and the shoe has expanded to your desired width or length.
Leave the Stretcher in Place:
Allow the wooden shoe stretcher to remain in place for several hours. The recommended time varies, but generally, it's best to leave it for at least six to eight hours. This duration ensures that the plastic fibres have time to adjust to the new shape and retain the stretch.
Remove the Stretcher and Try On the Shoes:
After the waiting period, carefully remove the wooden shoe stretcher from your plastic shoes. Now is the moment of truth—try on the shoes to check the new fit. Walk around in them to ensure they feel comfortable and have stretched to your liking.
Repeat as Needed:
If you feel that your plastic shoes still need a bit more stretching, don't worry. You can repeat the process as needed. Simply reinsert the wooden shoe stretcher, apply more tension, and allow it to remain in place for another cycle. With patience and persistence, you'll achieve the perfect fit.
Remember, when using a wooden shoe stretcher, always exercise caution and avoid over-stretching your plastic shoes. While this method can be effective, it's important to be gentle to prevent any damage to your footwear. Good luck with your shoe-stretching endeavours!

Take plastic shoes to a cobbler
While there are several at-home methods for stretching plastic shoes, taking them to a cobbler for professional stretching is always an option.
Cobblers have stretching machines that can increase the length and width of your shoes. They can stretch the toe box, the front of the shoe, or the sides of the shoe if your toes are feeling squished or your feet are feeling squeezed. They can also stretch the area around the ankle or calf by running their thumb between your skin and the shoe.
If you are unsure about whether a cobbler can stretch your plastic shoes, it is best to ask them directly. Some cobblers may be hesitant to stretch plastic shoes as they cannot be stretched very much without risking damage to the shoe. They may also be unable to stretch patent leather or other plastic-like materials.
If you are looking to stretch your shoes by more than half a size, it is likely worth taking them to a cobbler. They will be able to advise you on the best course of action and may be able to offer other solutions such as inserting thicker soles, tongue pads, or heel grips to improve the fit.
While taking your shoes to a cobbler may be more expensive than trying to stretch them at home, it can be a worthwhile investment to ensure your shoes are stretched properly and safely.

Frequently asked questions
Plastic shoes can be stretched using a hairdryer or blow dryer. Hold the dryer a few inches away from the shoe and heat the areas that feel tight in 20-30 second intervals. Walk around with the shoes on while they are still hot so that they can stretch and mould to your feet. You can also try freezing your shoes overnight. As the water inside freezes, it will expand and stretch your shoes.
One way to stretch your shoes without heat or freezing is to use an adjustable shoe tree. Turn the adjustable handle every 8 to 12 hours until you reach your desired length and width. Alternatively, you can try wearing your shoes around the house with thick socks on. The pressure of your feet in thick socks will help stretch out tight shoes.
Plastic shoes cannot be stretched very much without risking tears or holes in the material. If you are willing to take this risk, you can purchase a wooden shoe stretcher and crank it to the appropriate tension.
After trying one of the above methods, put on the shoes without socks and walk around in them. If they still feel too tight, continue stretching. If they feel right, great! If they are now too loose, you can try exchanging them for a smaller size.
