A rolling boot ( 10 ) for sealing two rotating parts ( 21, 22 ), which can be articulated and axially displaceable relative to one another. The rolling boot ( 10 ) has a first collar ( 11 ) with a smaller diameter for being secured on a first rotational part ( 11 ) with a smaller diameter, a second collar ( 12 ) with a larger diameter for being secured on a second rotational part ( 12 ) with a larger diameter, and an annular wall ( 13 ) whose diameter widens from the first collar ( 11 ) to the second collar ( 12 ). The annular wall ( 13 ), when the boot is at rest and unclamped, in half a longitudinal section, extends in an S-shaped way with an inner curvature next to the smaller first collar ( 11 ) and with an outer curvature next to the larger second collar ( 12 ).
