  In this work, we analyze a power-law inflationary potential enhanced with a
step that can introduce features in the primordial power spectrum. We focus on
the computation of the Spectral Distortions (SD) induced by these features
obtained from the inflationary dynamics. In this scenario, we explore the
potential of upcoming experimental missions like PIXIE to detect the SD of the
model within a power of $n = 2/3$, a power that agrees with recent
tensor-to-scalar ratio constraints. The model offers insights into models with
cosmological phases and different scalar field dynamics. Introducing a step in
the inflaton potential leads to distinct features in the primordial power
spectrum, such as oscillations and localized enhancements/suppressions at
specific scales. We analyze the impact of three primary parameters$-\beta$,
$\delta$, and $\phi_{\text{step}}-$on the amplitude and characteristics of the
SD. The $\phi_{\rm step}$ places the onset of the oscillations in the
primordial power spectrum. The $\beta$ parameter significantly influences the
magnitude of the $\mu$-SD, with its increase leading to larger SD and vice
versa. Similarly, the $\delta$ parameter affects the smoothness of the step in
the potential, with larger values resulting in smaller SD. Our findings
indicate a distinct parameter space defined by $0.02 <\delta/{\rm M_{pl}}
\lesssim 0.026$, $0.10 \lesssim \beta < 0.23$, and $ 7.53 \lesssim \phi_{\rm
step}/{\rm M_{pl}} \lesssim 7.55$, which produces SD potentially detectable by
PIXIE. This region also corresponds to the maximum observed values of $\mu$ and
$y$ SD, which in special cases are an order of magnitude larger than the
expected for $\Lambda$CDM. However, we also identify parameter ranges where
$\mu$ and $y$ SD may not be detectable due to the limitations of current
observational technology.
