Take a look at New Balance’s new Sonic Welded pack. Used mainly for technical clothing, tents and industrial fabrics, sonic welding is an environmentally friendly alternate to sewing or gluing. The process of heat and pressure application to the seams of pattern pieces fuses the shoe together cutting out waste and crafting the sonic welded shoe to be airtight and watertight. The pack consists of a 574 for men and a 410 for women. They will be available at Conveyor Fred Segal in Santa Monica starting May 13th.
