Alpha ($\alpha$) decay provides a sensitive probe of nuclear structure and remains one of the primary tools for studying heavy and superheavy nuclei. In this work, a systematic investigation of $\alpha$ decay is carried out using microscopic $\alpha$-nucleus potentials constructed from Skyrme Hartree-Fock formalism within a folding framework. The resulting potentials are constrained by the Bohr-Sommerfeld quantization condition and employed within a semiclassical WKB framework to calculate $\alpha$-decay half-lives over a broad range of even-even nuclei. The results suggest that the combination of microscopic Skyrme-based potentials and the Bohr-Sommerfeld constraint captures important aspects of the $\alpha$-decay process. The present study represents a first step toward a more microscopic description of $\alpha$ decay and motivates further developments beyond the local mean-field framework. References: [1] N.
