Avoids runners, keeping right (6)
I believe the answer is:
skirts
'avoids' is the definition.
(skirting is a kind of avoiding)
'runners keeping right' is the wordplay.
'runners' becomes 'skis' (ski is a kind of runner).
'keeping' indicates putting letters inside.
'right' becomes 'rt'.
'skis' going around 'rt' is 'SKIRTS'.
(Other definitions for skirts that I've seen before include "Finds a way round" , "Goes round the edge of - women's garments?" , "Minis, for example" , "Avoids the lower garment?" , "Lower garments" .)
