Moyes cleverly uses the symbol of shoes to represent identity. When Nisha loses her designer heels, she symbolically loses her wealthy facade, forcing her to confront who she truly is without the trappings of wealth. Conversely, Sam, by stepping into Nisha's expensive shoes, experiences a boost in confidence and a shift in her own self-perception. This theme explores how our external circumstances and possessions can influence our sense of self.

As Nisha and Sam navigate their increasingly intertwined lives, they begin to understand the struggles and complexities faced by the other. Nisha, stripped of her privilege, experiences the harsh realities of financial insecurity, while Sam grapples with the pressures and expectations that come with a life of affluence. Through their experiences, both women develop empathy and a deeper understanding of the challenges faced by those from vastly different walks of life.

At its heart, 'Someone Else's Shoes' is a story about second chances. Both Nisha and Sam are at crossroads in their lives, and the events of the novel provide an opportunity for them to reassess their priorities and make positive changes. The story emphasizes the power of resilience, demonstrating how even in the face of adversity, we have the capacity to adapt, grow, and ultimately, redefine ourselves.
