We discuss a new class of infrared-soft, Gribov copy-free gauges in which ghosts decouple. The gauges are natural for gauge theory, allowing a geometric interpretation of the Faddeev-Popov determinant in terms of the gauge-fixing flow on the space of gauge transformations. When a Nicolai-Langevin map is available, the new gauges are seen to be equivalent to Zwanziger's stochastic gauge fixing.
