Improved shoe soles with expanded thermoplastic polyurethane in one region
A recently filed patent (Publication Number: US20230309648A1) describes a unique sole design for a shoe. The sole is composed of two distinct surface regions: a first surface region made of expanded thermoplastic polyurethane (TPU), and a second surface region that does not contain expanded TPU.
The first surface region of the sole is made from expanded TPU, a type of plastic that has been heated and expanded to create a lightweight and cushioning material. This expanded TPU provides enhanced comfort and shock absorption for the wearer, making it ideal for use in shoe soles.
On the other hand, the second surface region of the sole does not contain expanded TPU. The exact composition of this region is not specified in the patent, but it is clear that it is different from the first surface region. This differentiation suggests that the second surface region may serve a different purpose or provide different properties compared to the expanded TPU region.
The patent does not provide further details about the specific design or construction of the shoe sole, focusing solely on the composition of the two surface regions. It is possible that this unique combination of expanded TPU and another material in the sole design could offer improved performance, durability, or other benefits for shoe wearers.
Overall, this patent filing introduces a novel sole design for shoes that incorporates expanded TPU in one surface region while excluding it from another. The specific advantages and applications of this design are not explicitly stated in the patent, but it opens up possibilities for further research and development in the field of shoe sole technology.
