The normal version requires level 78 Defence and degrades for 100,000 charges of combat before disintegrating - it cannot be repaired.
A corrupt version also exists, which requires only 20 Defence and lasts only for 15 minutes of wearing (degrades even while not in combat).
Due to the Evolution of Combat update, these platelegs now have stats that are equivalent to those of the Vesta's plateskirt. The Statius's and Vesta's equipment sets are now melee damage gear. In fact these platelegs are marginally stronger than Torva platelegs.
