The Bricks & Wood x New Balance 1906U 'Echoes of a Butterfly' represents the third collaboration between the LA and Boston brands. Inspired by the butterfly effect, the lifestyle runner features a black mesh upper with synthetic leather overlays in a gradient blend of yellow, crimson, fuchsia, black, teal and green. A butterfly graphic decorates the tongue, while 'Bricks & Wood' is inscribed on the lateral heel. The sneaker rests on a black foam midsole with pink-tinged ABZORB SBS cushioning in the heel.
