The Obi Moccasins are the perfect addition to your precision tripod. They've got the right amount of aggression and ample surface area to keep you stable in all conditons. They dig in hard and don't sink or slip in the sand/mud/dirt. And they don't add too much height or weight to your tripod. The Moccasins come as a set of 3 and are threaded 3/8-16 (RRS). They feature a tension washer that keeps them securely fastened - because nobody wants things unscrewing when you don't want them too!
