These are a set of three Rubber Suction Cup Feet from Manfrotto that also feature a retractable stainless steel spike. The suction cup increases the footprint of the legs by almost 20 times, giving much greater stability when needed. The steel tip provides a firmer footing on soft ground.

Manfrotto needs to go back to drawing board on this. The rubber feet screw on over the spike. Unfortunately they can unscrew and fall off easily. On a recent photo shoot I spent too much time backtracking to find the missing foot. On the plus side the wide feet are great when shooting on sand.
I got a set for my 728B digi compact tripod. The installation problem was the existing feet. They did NOT slip off. They were glued on with some clear, glass like, hard resin. The rubber feet had to be cut and then broken off. Then the shattered resin residue chipped out, which was like breaking off chunks of glass. When finally cleaned off the new feet went right on. The feet do improve the stance of this tripod significantly on many surfaces. The tripod still fits back into its original carry sack when oriented correctly, but just barely.
