They fit 3/8-16 threads and the rubber feet snap onto the spikes fairly securely. If I could change something it would be the length of the lugs (maybe 50% more, would be more versatile) and the stiffer rubber feet (their softness prevents a firm grip on the ground compared to the stiffer Gitzo feet). But for the rare photographers who appreciate the benefit, they work well.
