The two-fluid model for Helium II is used to derive the Mach number dependence on shock strength for weak fourth sound shock waves. The shock structure profile is found to be a hyperbolic tangent with shock thickness inversely proportional to shock strength. The steepening coefficient is evaluated, and methods for producing nonlinear fourth sound are discussed.
