Abstract
A shoe having an expandable shoe upper includes an outsole having a rear outsole and a front outsole and an expandable insole with a rear insole and a front insole. The front insole is movable relative to a length of the rear insole as the shoe upper expands from an unexpanded position to a fully expanded position. As the shoe upper expands, a gap is created between the heel and front outsole. At least one of the front insole and the rear insole covers the gap to protect a wearer's foot in an area of the gap when the shoe upper and expandable insole expand toward the fully expanded position.
