The Nike Air Monarch IV 'Black Blue' makes use of a straightforward color scheme that complements the sneaker’s clean lines. The all-leather upper features a crisp white base with contrasting black overlays and vibrant pops of blue on the tongue, Swoosh and toe. A white phylon midsole packs a full-length encapsulated Air-Sole unit for lightweight cushioning, while the multi-pattern rubber outsole offers durable traction.
