Aim of the Research: Selection of the footwear material in the past few yearshas become very complex and monotonous process due to customer’s increasing demand for fashionable and durable footwear. Now customer prefer to buy those footwear which are designed with using lubri-crativeor fancy colors, good design and quality which are not only suits their personality and reflects their personality in the society. Customers are willing to spend additional price, if they get sports shoes which providethem additional comfort in terms of shock absorption, fit, durability, color, motion controland suits their overall attire. In leather made sports shoe, there is always a chance of scarcity of leather, due to reducing cattle stock day by day and prohibition on animal killing in the country. On the other hand P.U. polyurethane is easily available in the country in all the quality and price ranges. There are many other unique and important characteristics of P.U which made it the first choice of sports shoe manufacturing be-national and international brands. Hence, the aim of the research paper is to identify how the Polyurethane P.U (which is extremely versatile elastomer having an excellent property of damping i.e., absorption of pressure) as material is gaining importance in construction of upper and bottom components of footwear as to meets both the expectations of the end user. Research Methodology: The research methodology is based on review and analysis on secondary data – cases, literature review and government reports. A comparative report will be made on the basis of the past literature keeping in mind the need of future. A research design is completelyrely of descriptive research. Key Findings: The outcome of the study enlightened how P.U. has been most demanding material in present as it meets the expectation level of customers due to its scientific properties and easy to processed as per the current trends prevailing in the market, moreover it provide additional benefits like cushioning, flexibility, tensile strength. Contributions: 1. Sports shoe Manufacturer: to understand the benefits of polyurethane for production of sports shoe. 2. Customers: to understand and the selection the quality and benefits of P.U. in sports shoe and get desired level of performance & meeting cost elements.
