Usage notes
Beware that and  are used in the opposite sense from /, in which talk means “words without action” and walk means “action”. Here talk is used metaphorically to means “has actual effect, shows seriousness”, as in similar, instead of in the sense “empty words, without impact”, as in and ; walk is used to mean “walks away, does not follow through”.
