TPR is the most used material in soles of footwear because this sole offers superior comfort to ordinary die cut soles, because it is flexible like a traditional leather sole but also washable and more durable. It is the  conventional and popular material for injecting the soles,but in daily life,many people don't know whether the shoes they wear are made of TPR. 

Advanatges - Light in weight, Good tear strength, Excellent abrasion resistant, Excellent weather resistant , Reusable and recyclable.

Polyurethane or PU Sole -

This is a type of dense foam that provides a great deal of cushioning and shock absorption for a longer period of time. Because it is so dense it can feel heavier, seem stiffer, and may not feel quite as cushioned as shoes that use EVA. It is most commonly used in walking shoes because it provides a great deal of stability and comfort.

Disadvantages: easy to break, elongation is poor and poor ventilation.

PU sole is great and tough you can wear it for very long period and duration.
