Why Redback Boots Chose TPU Soles

There are several materials which make for a good choice with regards to being used as a sole for footwear. Traditionally, materials like natural rubber and leather were used as they offered the most comfort and longevity. 

This all changed with the creation and discovery of new materials such as TPU, EVA, PVC and many others. In particular, TPU has become a stapple choice for many footwear brands. It provides excellent traction, good foot impact absorption and is highly resistant to chemicals, oils and high temperatures, making it a good choice for workwear. However, there is one negative to the material and that is the issue of hydrolysis;

This is why we always recommend keeping your boots dry and in a cool, well ventilated area and that you wear the boots on a regular basis. Hydrolysis occurs when water molecules are trapped within the TPU substrate and are unable to escape. The physical action of walking (compressing and flexing the rubber) helps release the water molecules from the TPU. If water molecules accumulate in the TPU, chemical deterioration is also accelerated. In extremis, this can result in TPU failure in the form of crumbling or splitting. These issues are not generally covered by our warranty hence why we emphasize the importance of regular cleaning, drying and maintenance of your Redback boots.

So to summarize, if you keep you boots clean and dry and you wear them regularly, they will last a really long time. We have many customers returning to us for their second pair of Redback boots after five years or more. We have seen plenty of good examples lasting over 10 years. 

Thank you for your time.
