New Balance joins Nike, Adidas and others in the race to gain a foothold in the 3D printed shoe market. NB has announced a new $400 sneaker that utilizes additive manufacturing. As technology develops, shoe companies are looking for new, innovative ways to make shoes stronger, more comfortable, more versatile and adaptive. The sneaker touts a new porous insole that molds to the wearer’s foot. This is another example of how 3D printed wearables are becoming more prominent and how the expansion of 3D printing technology is spurring creativity in industry. Time will tell if the industry has put its right foot forward.
