Without footwear (8)
(Other definitions for barefoot that I've seen before include "'-------- in the Park', Neil Simon play filmed in 1967 with Jane Fonda and Robert Redford" , "Shoeless" , "Without shoes and socks" , "Unshod" , "without protection for lowest members" .)
'without footwear' is the definition.
('footwear' can be 'shoe' (shoe is a kind of footwear) so maybe 'without footwear' can be ''shoeless')
This is the entire clue.
(Other definitions for shoeless that I've seen before include "like Joe Jackson?" , "Unshod" , "Having no use for trainers" .)
