Shoes can be quite delicate and may not respond well to hand washing, especially when it comes to intentionally trying to shrink them. The outcome of hand washing shoes is unpredictable and can vary depending on the material and construction of the shoes. Additionally, some shoes may lose their shape, color, or structural integrity when exposed to water and soap.
If you're looking to shrink shoes because they are slightly too big, there are other methods you can try before resorting to washing:
Insoles or Inserts: You can add insoles or padded inserts to take up extra space and make the shoes fit more snugly.
Thicker Socks: Wearing thicker socks can also help fill up some of the extra space inside the shoes.
Adjustable Lacing: If the shoes have laces, try adjusting the lacing to provide a tighter fit.
Shoe Inserts or Heel Grips: These products are designed to prevent the heels from slipping and can make the shoes fit better.
If the shoes are too big and none of the methods mentioned above work for you, it might be best to consider exchanging them for a smaller size or trying a different style that fits better.
In general, it's essential to follow the care instructions provided by the shoe manufacturer to maintain the shoes' quality and appearance. If you're unsure about cleaning or altering your shoes, it's a good idea to consult a professional cobbler or shoe repair service for advice specific to your shoes' material and construction.
