1. The stainless steel replacement feet can be screwed into the threaded 3/8" -16 holes at the ends of the tripod legs. 2. These feet allow the tripod leg to dig deep into soft surfaces in the terrain, creating a stable base with the ground when you photograph on softer, looser terrain. 3. The universal 3/8" -16 stud at the top allows you to use them with all brands that use standard 3/8" -16 threads. 4. Compatible with Gitzo, Manfrotto, Siri, Benro, and other tripods with standard 3/8" threaded feet and/or monopod feet. 5. They are the perfect way to keep your tripod stable when photographing on softer, looser surfaces such as snow, sand, soft soil, gravel, and other loose surfaces. They are also useful on carpets. Tighten the foot with an Allen key.
