A lot of shoes feel great straight out of the box, but before you know it they start to fall flat on the job. But New Balance 840v4 Sneakers will keep the bounce in your step mile after mile, thanks to ABZORB® cushioning technology that takes a pounding and keeps on rebounding. The mesh upper lets fresh air flow through, blowing off heat and sweat for a cool ride – even when you’re running at a feverish pace. And the entire shoe is constructed without chafing sewn seams so you can go the distance without blisters or hot spots.
