In July 2017, Ronnie Fieg collaborated with New Balance and Dover Street Market to introduce the 574 Sport sneaker, bringing forth three distinct color variations. Specifically, the 'Navy' rendition pays homage to Fieg's treasured 574J color scheme. Crafted from high-quality nubuck material, the shoe showcases perforated panels and exclusive co-branded insoles. Additionally, an alternative set of laces is provided to offer versatility. Another highlight of this model is the interchangeable velcro 'N' logo, allowing wearers to customize their look by opting for various leather, nubuck, or reflective options from a selection of 28 alternatives.
