Why Redback Boots Chose TPU Soles

There are several materials that make a good choice for use as a sole in footwear. Traditionally, materials such as natural rubber and leather were used, as they offered excellent comfort and longevity.

This changed with the creation and discovery of new materials such as TPU, EVA, PVC, and many others. In particular, TPU has become a staple choice for many footwear brands. It provides excellent traction, good impact absorption, and is highly resistant to chemicals, oils, and high temperatures, making it a strong choice for workwear. The soles are also non-marking. However, there is one drawback to this material: the issue of hydrolysis.

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

To summarise, if you keep your boots clean and dry and wear them regularly, they will last a very long time. We have many customers returning to us for their second pair of Redback boots after five years or more and we have seen plenty of examples lasting over ten years.
