Acceptable footwear sailor finally carried towards land (7)
I believe the answer is:
onshore
'towards land' is the definition.
(I've seen this before)
'acceptable footwear sailor finally carried' is the wordplay.
'acceptable' becomes 'on' (I've seen this in other clues).
'footwear' becomes 'shoe' (shoe is a kind of footwear).
'finally' suggests the final letters.
'carried' indicates putting letters inside (one word carried by another word).
The final letter of 'sailor' is 'r'.
'shoe' placed around 'r' is 'shore'.
'on'+'shore'='ONSHORE'
(Other definitions for onshore that I've seen before include "Away from the sea" , "beach?" , "(Of wind) blowing from sea" , "coming in from water" , "towards the coast" .)
