A work boot has an anatomical tongue that is asymmetrical about a longitudinal line of the tongue extending vertically upward from a mind-point of a bottom of said tongue. The tongue contains memory foam and shapes itself to a particular user. The memory foam causes the tongue to retain its shape. The side walls of the boot have J-bars extending inward therefrom. The J-bars also contain memory foam to comfortably fit the foot of a particular user.
