India’s ethnically diverse population presents unique challenges in designing and developing shoe lasts that adequately accommodate varying foot dimensions. While global footwear sizing systems are often based on Western population data, Indian feet exhibit distinct morphological characteristics, such as wider forefeet, higher arches, and shorter toe lengths in some groups. Geographic, genetic, and cultural factors further influence these variations, which are envisaged in the process of shoe last development in this research work. The casual shoe last EU Size 42 (Male) was taken as the template for designing and developing the shoe last based on 3D foot models of the Indian Male population. Parameters like foot width, heel width, ball girth, and instep girth required significantly higher measurement values to fit the Indian foot anatomy perfectly. The footwear last serves as a fundamental interface between feet and shoes, fundamentally influencing footwear’s style, shape, comfort, and fit.
