The wait is finally over as UNDEFEATED rearranges the classic New Balance M574 running model. New Balance recently introduced the new welding technique, Ultra Sonic Welding which is used on all Sonic Concept models. MS574 model that was chosen for this collaboration project is part of that concept and utilizes the welding method beautifully. The almost seamless welding is hidden further by the unique choice of upper material, 1980's vintage sweat top fabric. Tricolor N logo on the side is a subtle patriotic touch and UNDEFEATED woven logo is stitched on the heel of the insoles.
