    Adoption of the lean manufacturing philosophy is currently seen as a necessity since it is a differentiating and successful element to ensure high competitiveness in the market. LIWI medical, an Ecuadorian company dedicated to the manufacture of orthopedic footwear at national level, presents a lack of control over its value chain and production processes, wasting the maximum of its capacity, creating a negative impact on its production costs, productivity. Therefore, the objective of the research project focuses on a proposal for improvement through appropriate lean manufacturing tools, which will have a positive impact on the footwear production line by reducing waste and thus improving its capacity. Using industrial engineering tools, information is gathered to determine the current situation of the company and, above all, to identify and describe the production activities. To find the waste, the value stream map is applied to establish the activities that do not add value to the process. For the selection of operational tools, the hierarchical analytical process methodology is used, showing that the tools with the greatest impact are: 5s and quick tool change, which allow reducing or eliminating waste. Likewise, a simulation model of the process is designed in the FlexSim program, with the improvement proposals. The results show that the application of lean manufacturing tools improves process efficiency by reducing the takt time by 30.28%, achieving the production of 45 pairs per day, representing an improvement of 22.86%, with a productivity of 1.30, which improved by 2.36% compared to the current situation, improving the production system
