We discuss the status of determination of the strong coupling with special attention to using event shape observables based on data collected at the Large Electron Positron collider and theoretical predictions at highest accuracy available at present. We argue that such extractions can be competitive with lattice determination if the observables are selected carefully such that both higher order perturbative as well as non-perturbative contributions are suppressed.
