Why Shoe Sole Material Matters More Than You Think

Sole material is the unsung hero of footwear, providing the frontline defensive barrier between your foot and the ground. Without a high-quality shoe sole material, you may as well be walking barefoot, inviting a range of potential injuries and other risks. 

Sole material, and shoe comfort, in general, are more important than you might realize. Studies show that over 60% of Americans wear shoes that hurt their feet, and one-third say that foot pain has sidelined them from everyday activities. If you’ve been suffering from footwear woes, sole material might be at the bottom of it (pun intended). 

Shoe sole material is a fundamental aspect of footwear design, determining the overall comfort, support, and durability of a shoe. Read on to discover our comprehensive guide on sole material, including its role in foot health, performance quality, durability, and more. 

 

The Role of Shoe Sole Material in Foot Health

A whopping 78% of Americans report foot problems from uncomfortable shoes. You may assume this has to do with the price of fashion—after all, wearing high-heeled shoes will inevitably cause pain and discomfort, right? But the truth is, any type of shoe, whether it’s a flat or a platform, should facilitate your foot comfort, not impede it. 

Shoe sole materials play a pivotal role in shoe comfort and resistance and, as a result, foot health overall. If you’re struggling with chronic foot pain, the problem may not be the shoe style or fit—it might have to do with the material and durability of the sole’s construction. 

Consider these ideal sole characteristics in your footwear:

At Vionic, we’ve kept all these factors in mind—our footwear is designed with contoured footbeds, flexible soles, and shock-absorbing technology.

 

Preventing Common Injuries

Many foot issues can be easily prevented by simply seeking out the right shoe sole materials. First, consider traction and stability. If your shoe slips around on uneven or wet surfaces, you’re one misstep away from a twisted ankle. Even a rubber sole without any grip on laminate flooring can cause a foot or ankle injury. 

Sole material is more than just the what of a shoe’s underside. It also plays an important role in foot alignment—that is, how your feet move, position, and connect with the ground. The sole provides support, stability, and balance throughout the day, and absorbs shock from high-impact activities. Without these benefits, you’re more prone to injuries and long-term pain.   

Low-quality or improper sole materials can lead to a range of footwear-related injuries, including:  

Remember that everyone has different foot shapes, so once you cover the basics in this guide, the best sole material will depend on your unique needs and health concerns (more on that in a minute). 

 

Performance Benefits of Quality Shoe Sole Material

You don’t have to be a competitive athlete to consider the performance qualities of your footwear. Whether you’re on your feet all day at work, hiking on the weekends, or jetting across the airport to your next international voyage, sole material promotes foot health and overall comfort. 

All shoes undergo everyday wear and tear, so a high-quality sole is essential to provide the following: 

With a flexible yet supportive sole, you’ll have the freedom to move wherever your day takes you. 

 

Comparing the Best Shoe Sole Material

Shoe soles come in many shapes and sizes, and the type of material usually has to do with footwear function. For instance, you wouldn’t expect the same adaptability from a waterproof sandal as you would from a walking sneaker. 

Let’s break down three of the most common and versatile materials for shoe soles.

 

EVA Soles

EVA is a flexible foam material made from polymer plastics. It excels as a shoe sole thanks to its lightweight nature, cushioning properties, and natural moldability. The shock absorption of EVA shoe material is perfect for walking and other active shoes.  

 

Rubber Soles

Natural rubber provides a sturdy outsole with unbeatable traction and durability. When you’re investing in a long-term shoe, you can’t go wrong with rubber soles. Plus, it’s a waterproof material, which comes in handy for poolside summer days. 

 

Polyurethane and Other Synthetics

Polyurethane is a synthetic polymer used as a foam material for shoe soles. It can easily be made more or less flexible depending on the desired shock absorption. Other synthetics, such as synthetic rubber, can also be specifically developed for use in durable shoe soles. 

 

Tips for Selecting the Right Shoe Sole Material

So, now that you understand the importance of shoe sole material, you may still be wondering: what’s the best material for me? There are various lifestyle factors to consider, but we want to highlight two key aspects: 

If you’re still unsure where to start, you can have your feet professionally fitted or consult with a podiatrist. 

 

Long-Term Implications of Shoe Sole Material Selection

No matter the sole that’s best for your feet, one thing is universal: choosing a sole material for shoes’ long-term wear and tear. High-quality, durable shoe sole materials are a must for enjoying your footwear for years to come. 

An investment in a high-quality sole is also an investment in your foot health. Soles that lack cushioning, are made from low-quality materials, or provide no flexibility will not only wear down faster, but are more likely to cause pain and injury.
