These are very good nuking feet for SCH. While other pieces will provide better dmg boosts on regular nukes. These feet add a 10% DMG bonus when properly using Klimaform and nuking in aligning weather.
In addition to that the 10 ele skill is pretty nice and nuking in these adds yet another piece to proc the quick cast set bonus. Which over time will far outweigh any other feet you could possibly nuke in.
