Over the years many different types of fits for the strong coupling
constant have been performed. However one type of high precision result
that currently significantly differs from the world average are results
from event shapes at electron positron colliders. One possible source
for the difference in these results could be the degeneracy between
the fit of the strong coupling constant and non-perturbative parameters.
In this talk I will explore the application of modern jet substructure
techniques, specifically soft drop, in order to break the impact of
the non-perturbative corrections on the fit of the strong coupling
