Helinox says:
Equip select Helinox Chair with more stable footing on soft ground and sand by using the silicone Helinox Ball Feet Set 45mm. Sold in sets of 4, the silicone feet have a press-fit design that allows them to slip easily over top of the existing feet.
Helinox's 45mm Ball Feet add about four times the surface area of each regular Helinox chair foot, so you're much less likely to sink in to the ground anywhere even at the beach. They're also a nice addition for those of you who use your Chairs in tents, the extra surface area ensures you're not going to damage your groundsheet.
