For casual travel days, Dr. Biden has been spotted in her skull Stubbs and Wootton slippers, which retail for $500 and are hand-crafted in Spain. The skull embroidery is proof Biden is more than willing to add a touch of personality to her looks — and that she's realistic about navigating the lawn in sensible flat loafers, rather than heels. Stubbs and Wootton, founded in the early '90s in Palm Beach, Florida, prides itself on making luxury, bespoke slippers relevant.
