About the New Balance P400 'Black'
The New Balance P400 'Black' gives the performance basketball shoe a stealthy monochrome makeover. The molded synthetic leather upper is accented with a molded 'N' logo on the quarter panel. Disrupting the tonal design, 'New Balance' is printed in white lettering atop the tongue. The sneaker is mounted on a matching black EVA midsole that houses a Fresh Foam X core, along with a nylon plate that offers torsional rigidity and energy return.
