Using the Peak Design Spike Feet Set is a breeze. First, take off the standard rubber feet from your Travel Tripod. Then, use the included hex wrench to attach the three spike feet to the tripod legs with the hex - drive screws. These spike feet are great for shooting on slippery or loose terrain like ice, smooth rocks, or gravel, and also work well with heavier photo or video rigs. When using them, make sure the screws are tightened properly to ensure stability. After use, it's a good idea to clean the spike feet with a dry cloth to remove any dirt or debris. Store them in a dry place to prevent rusting. And remember, they're compatible with both Peak Design Carbon and Aluminum Travel Tripod models.
