The concern for a greener production and more consciousness consumption is increasingly present in global discussions across all industries, including the sports footwear industry, which produced approximately 20 billion pairs of shoes in 2023. The focus on health and the growing visibility of sports activities contribute to the consumption and waste growth generation in this sector, ultimately compromising environmental sustainability. The use of green marketing strategies aims to conceptualize the design, production, and consumption of products in a sustainable manner, through the elements of the marketing mix, throughout the product lifecycle. Therefore, this research aimed to analyze and compare green marketing strategies adopted by major brands in the sports footwear segment using the 4Ps of the marketing mix and evaluate whether they are perceived as effective by the market. To achieve the proposed objectives, a qualitative approach of multiple case studies was employed by analyzing publications from independent organizations in the sector as well as reports, videos, and interviews published by the analyzed sports brands. The study identified that all studied brands implement green marketing strategies, but at different levels of maturity, and not throughout the lifecycle of the products, nor even for all products within their lines, leading to varying perceptions of the effectiveness of these strategies by the market.
