New Balance has reintroduced Sonic Weld technology to one if its classic running models.? The New Balance 574 uses the eco-friendly innovation on simple Grey/Yellow and Brown/Orange colorways.? The uppers consist of suede and mesh, implementing Sonic Weld technology in favor of stitchwork resulting in a clean and seamless look.? A white midsole atop a black oustole sets the stage for both 574’s for simplicity.? The Brown/Orange pair uses all brown suede and mesh on the upper with an orange heel cap while the Grey/Yellow pair uses grey suede and mesh up top with a yellow heel cap.? We previewed this Sonic Weld lineup in May and are happy to say that these two colorways are available now at NB Web Express.
