Versatile Vanz from 3 Legged Thing are longer tripod feet which can be added to raise the height of your tripod above rough terrain and can be used with ABS balls that can be removed to reveal spikes. The 3 Legged Thing Vanz Set of 3 Spikes + Rubber Feet have been designed to work in conjunction with the 3 Legged Thing Legends tripods; although they're compatible with all 1/4""-20 and 3/8""-16 threads. The kit enables the use of your tripod on a variety of terrains as well as converting your tripod for table-top use. Furthermore, the spikes will elevate your tripod off the ground, clear of damaging surfaces/materials, as well as providing added stability.
