A shoe apparatus with electronic grip enhancement is disclosed. In particular, the shoe includes: an electrical energy storage device such as a capacitor or battery; a piezoelectric generator configured to generate electricity when the user takes a step in the shoe; and a sole including an electrostatic adhesive portion configured to augment the grip of the shoe.

A footwear combination that includes a base shoe that may be combined with plural different fitted socks to accommodate plural outfits, depending upon the fitted sock that is combined with the shoe.
