In preparation for the northern spring, New Balance flip a colourway ideal for the season of blossoming plantlife and animals doin' the nasty. Officially listed as Happy Blue / Bright Yellow, this might be one of the most optimistic palettes we've ever seen. It's also a crazy fresh looking flip of the 574, with tonal blue suede and mesh paneling complemented by pops of striking yellow. Look for these at New Balance retailers as part of the NB spring collection. Pics via The Toe Box.
