Waterproofing is the process of making an object or material resistant to water. This concept is not limited to clothing and footwear but applies to various products such as tents, backpacks, and electronics. This article will focus on the science behind waterproofing in trainers, a common type of footwear.

What is waterproofing in footwear?

Waterproofing in footwear refers to making shoes or trainers resistant to water. This is done by putting a waterproof coating or membrane on the shoe. This coating or membrane is a barrier preventing water from entering the shoe polish.

Why is waterproofing important for trainers?

Trainers are commonly worn in various weather conditions, including rain, snow, and slush. If the trainers are not waterproof, the feet can become wet and uncomfortable, leading to various issues such as blisters and fungal infections. Furthermore, wet trainers can also lead to water damage, which can reduce the lifespan of the trainers.

Types of waterproofing materials used in trainers

There are various materials used for waterproofing trainers, including:

Polyurethane (PU)

Polyurethane is a synthetic material commonly used for waterproofing footwear. It is lightweight, flexible, and durable, making it an ideal trainer choice.

Polyvinyl chloride (PVC)

Polyvinyl chloride is a plastic material commonly used for waterproofing footwear. It is known for its durability and resistance to water, making it a popular trainer choice.

Gore-Tex

Gore-Tex is a membrane technology that makes shoes waterproof and breathable. Trainers and other types of shoes use this technology. It is known for keeping feet dry while allowing for breathability.

How waterproofing works in trainers

Waterproofing in trainers works in several ways, including:

Sealing the seams

The seams of the trainers are sealed to prevent water from seeping through. This is achieved by applying waterproof tape or coating to the seams.

Membrane technology

Waterproof shoes use membrane technology to make a barrier between the feet and the water. The membrane is made of a material that is both waterproof and breathable, so it can keep water out and let air in.

Durable Water Repellent (DWR) treatment

A durable water repellent (DWR) treatment is applied to the trainers' surface to make them water-resistant. This treatment causes water to bead up and roll off the surface of the trainers, preventing it from seeping through.

Advantages of waterproofing trainers

There are several advantages to waterproofing trainers, including the following:

It keeps feet dry.

One of the main advantages of waterproof trainers is that they keep feet dry even in wet weather conditions. This helps prevent blisters and other foot problems that can occur when feet are wet for an extended period.

Protects against water damage

Waterproofing also helps protect against water damage, which can reduce the lifespan of the trainers. This is especially important for those who frequently wear their trainers in wet weather conditions.

Increases the longevity of trainers

By protecting against water damage, waterproofing can also increase the longevity of the trainers. This is because the trainers are less likely to become damaged or worn out due to exposure to water.

Disadvantages of waterproofing trainers

There are also some disadvantages to waterproofing trainers, including:

Can impact breathability

While waterproofing helps keep feet dry, it can also impact breathability. This is because the waterproof coating or membrane can trap heat and moisture inside the trainers, making them less breathable.

It can be expensive.

Waterproofing trainers can also be expensive, especially if the trainers are made from high-quality materials or the complex waterproofing process.

Maintenance of waterproof trainers

To keep trainers waterproof, it is essential to follow the care and maintenance instructions from the manufacturer. This may include regular cleaning and reapplication of the waterproof coating or membrane.

Testing the waterproofing of trainers

There are several ways to test the waterproofing of trainers, including:

• Wearing them in the rain or shower
• Submerging them in water
• Spraying water on the surface of the trainers

Different brands and products offer waterproof trainers.

Some many brands and products offer waterproof trainers, including:

• Adidas Terrex
• Columbia Redmond Waterproof
• Merrell Moab 2 Waterproof
• Nike ACG Air Zoom AO
• The North Face Hedgehog Hiker Waterproof

Conclusion

In conclusion, a waterproofing trainer is a necessary process that helps keep feet dry and protects against water damage. While waterproofing has some disadvantages, such as reduced breathability and increased cost, the benefits far outweigh these drawbacks. Waterproof trainers can provide years of protection and comfort by following the manufacturer's instructions for care and maintenance.
