Antibacterial shoe insole technology

Hiking boots and insoles airing

Polygiene Freshness solutions eliminate odors in textiles, making them ideal for products that are in regular contact with one of the smelliest areas of the human body – the feet! While some anti-odor solutions utilize antibacterial technology to deal with unpleasant odors in footwear, others use silica-based antibacterial shoe insole technology. Here, we explore the difference between the two and how both types of solutions are employed to protect shoe insoles.

What are antibacterial shoe insoles?

Antibacterial shoe insoles prevent the growth of odor-causing bacteria in footwear. This helps to minimize and eliminate bad smells, keeping your shoes smelling and feeling fresher for longer. Specialist antibacterial insoles tend to integrate advanced additive technologies, such as Polygiene StayFresh™. In contrast, solutions like Polygiene OdorCrunch™ use silica-based technology to combat environmental odors. While both help keep odors at bay and enhance comfort, the former targets bacterial odors and the latter tackles the molecules responsible for bad smells.

Understanding why odor control in insoles is so important

Foot and shoe odor are common issues that affect many people and significantly impact comfort and self-confidence. Understanding why the feet pose such a considerable problem gives us valuable insight into why antibacterial shoe insoles are so effective.

  • The average pair of human feet have around 250,000 sweat glands, more glands per square inch than anywhere else on the body, and often produce approximately half a pint of sweat a day (NHS).
  • The average pair of shoes typically harbor millions of bacteria, including many potentially harmful bacteria like C. diff. (BestCare).
  • Research indicates that unwashed and untreated trainers often contain more bacteria than your average toilet seat (Express).

Bacteria are one of the most common causes of unpleasant odors and are particularly problematic when concentrated in textiles, apparel, and footwear. Tackling bacterial growth is one of the most efficient and effective means of preventing bad smells in footwear.

The benefits of using antibacterial shoe insoles

Antibacterial shoe inserts benefit users in several ways.

Antibacterial insoles prevent odor-causing bacteria from growing and proliferating. This minimizes the smells they produce as part of the metabolic process. The fewer bacteria, the less your feet and shoes smell.

Personal odors are a big self-confidence issue for many people. Unpleasant smells can make us feel incredibly self-conscious and influence our behavior. For instance, many people may feel uncomfortable removing their shoes in indoor spaces and avoid environments where that may occur. By keeping our feet and shoes fresher for longer, shoe insole odor-control solutions empower users and enable them to be more comfortable and confident.

When your shoes smell less, you don’t have to wash or clean them as frequently. Reduced maintenance means less hassle for users.

The washing process is hard on textiles and is one of the primary causes of premature wear and tear. This is particularly true of fabrics we clean in the washing machine. By reducing the frequency with which you need to wash your insoles and footwear, antibacterial, anti-odor shoe insole technology extends a product’s expected lifespan.

Machine washing is a resource-intensive process that consumes large amounts of water and electricity. The more regularly you wash your insoles or shoes, the less environmentally friendly the product is. Similarly, shoes that last longer are replaced less often, further enhancing their overall environmental performance.

The drawbacks of traditional insoles

Standard insoles offer no antibacterial protection. In fact, they provide bacteria with the perfect conditions for growth. They typically absorb and retain sweat, creating the damp and warm conditions in which odor-causing bacteria thrive. Over time, insoles capture and amplify these odors, compounding the problem. The only solution is to wash the insoles, which not only results in premature wear but also does nothing to prevent the bacteria and bad smells from returning.

The science behind antibacterial shoe insole technology

The Polygiene StayFresh solution utilizes silver ion technology to combat bacterial growth. This technology is based on silver chloride – a salt that occurs naturally in water and soil – and has been extensively tested and proven to be completely skin-safe. It combats bacteria in three distinct ways:

  1. It binds with the bacterial cell wall and prevents growth.
  2. It inhibits enzyme production, affecting the cell’s ability to produce energy.
  3. It disrupts cellular DNA, preventing bacteria from replicating.

Polygiene’s approach to antibacterial additive solutions is renowned for its efficacy, ease of application, and longevity. Integrated into materials at the point of manufacture, it provides 24/7 protection, keeping your shoes fresher for longer.

Other Polygiene anti-odor solutions for insoles

However, Polygiene StayFresh isn’t the only anti-odor solution in our product portfolio. Polygiene OdorCrunch leverages advanced silica-based technology to tackle body and environmental odors. The natural silica particles in the solution capture the molecules responsible for bad smells that cling to fabric fibers, such as oxygen, nitrogen, and sulfur molecules.

They then surround the molecules and “crunch” them, breaking them down and nullifying the odor. It is a highly effective solution for insoles, especially when combined with Polygiene StayFresh.
