I think the sentence could be made more correct by replacing shoes with booties. Baby booties are the thick, typically woven, often hand-woven footwear used to keep a baby's feet warm. They're often gifted by family to the expecting parents and sometimes kept as a keepsake, so someone getting rid of never-worn booties works a little better. Though it's typically considered distasteful to sell handmade gifts. Of course, the sentence seems to work fine as a story regardless of its correctness, based on its enduring popularity.
