STARFLEET UNIFORM BOOTS :

Worn by NICHELLE NICHOLS”

From It's A Wrap Auctions :

The boots feature long inside zips, slight heels, an expansion area behind the zip, tan interiors, and black exteriors. The inside of the boots are both inscribed "N. Nichols" and thus are believed to have been worn by actress Nichelle Nichols in her portrayal of “Uhura”. The boots are in used condition and depict some slight scuffing on raised edges and around the toes, but nothing distracting for display purposes.
