Leave big shoes to fill

Origin

The metaphor of 'shoes' as a stand-in for a person's role or position has been part of English for centuries; we 'step into someone's shoes' when taking over their duties. However, the addition of 'big' to this well-worn phrase is a more recent flourish, gaining traction in the 20th century as the cultural focus shifted towards celebrating individual achievement and lasting legacies. The phrase vividly conjures the image of a successor struggling to adequately fill the expansive, perhaps even oversized, footwear of a predecessor whose accomplishments were so towering, their influence so vast, that their replacement faces an almost insurmountable challenge. It captures the immense pressure and high expectations placed on those tasked with following true greatness.
