New Balance has updated their classic 574 silhouette with a fresh, modern-day look. By using sonic welding, they were able to replace the customary stitched panel uppers for lightweight nylon uppers. This process uses high frequency sound waves to bond the materials together. In the image shown we see a grey and black mesh upper with bright yellow and lime accents. You can find the New Balance 574’s at select stockists now, including Hype DC.
