Why polyurethane soles on your work boots?


Choosing your boots is already a complicated enough step for many that the material of the sole can quickly be forgotten. But have you ever wondered: Why are the soles of my boots made of polyurethane?

There are excellent reasons why this material is the choice of companies like Kosto when designing the soles of your work boots.

First of all, what is polyurethane?

This material dates back to the early 1930s and was originally intended to replace rubber due to its exorbitant price. This plastic derivative has a relatively standard composition, enabling the material to be produced in various forms: rigid, flexible, and even foamy!

Its versatility has enabled polyurethane to establish itself in the manufacturing market as an essential, and almost 100 years later, it continues to grow in importance in many fields of innovation!

Polyurethane soles also offer specific advantages in safety boots or any type of footwear. 

Here are just a few of their benefits:

Polyurethane soles are generally lighter and more flexible than other materials, making them comfortable to wear all day. They offer good cushioning to reduce pressure on the feet, which is particularly beneficial if you work on hard surfaces or stand for long periods.

Polyurethane has excellent shock-absorbing properties, helping to lessen the impact on your feet and joints. This can help prevent pain and injury associated with repetitive impact or high-impact activities.

Polyurethane soles are abrasion-resistant, which means they have enhanced durability and can withstand prolonged daily use. They are less likely to wear out quickly, extending your boots’ overall life.

Polyurethane soles offer flexibility, facilitating the foot’s natural movement when working. They provide good flexion and grip on the ground, improving stability and reducing the risk of slips or falls.

Polyurethane has a low thermal conductivity, which offers thermal insulation for your feet. This can be beneficial if you work in cold environments, as it helps to maintain a comfortable temperature and prevent hypothermia.

The proof of PU’s insulating power is in the pudding—your home and refrigerator are two of the biggest beneficiaries of urethane insulation!

Polyurethane is also resistant to many chemicals commonly encountered in the workplace, such as oils, greases and certain acids. So it offers your feet extra protection against potentially hazardous substances.

You should also know that polyurethane soles can vary in density and composition according to shoe brands and models. So choosing quality footwear is essential, and ensuring it meets the appropriate safety standards for your specific working environment.
