Summit Hut says:
Snowballing adds weight and can eliminate traction, especially in mushy spring conditions. Made of durable, reinforced neoprene that wont crack or freeze, the SRS is Kahtoola's version of an anti-balling plate for crampons but theirs are the lightest in the industry! Fits all sizes of KTS steel and aluminum.
Compatible with: Kahtoola KTS Hiking Crampons,
