Back in January of this year, New Balance unveiled its New Balance 410 Slim Pack, which not only boasted a slimmer fit but also no signs of stitching. Now the brand has once again chosen the New Balance 410 silhouette as the shoe palette for further innovation. Pictured here are two pairs of the New Balance 410 Sonic. These shoes implement sonic welding- an environmentally friendly alternative to gluing or sewing, into the shoe-making process. The sonic welding also helps make each pair of shoes be more air and water tight. The New Balance 410 comes in women’s sizes and in a black/grey or grey/pink colorway. You can pick these up now at participating New Balance retailers.
