This technology is really representative of natural running shoes such as Altra Running: it is actually setting this brand apart from other performance shoes, promoting happy feet.

Its toe box follows the shape of a healthy foot for a better comfort, balance and running efficiency:

• places foot in its proper and natural position;
• allows toes to relax and spread out naturally;
• maximizes shock absorption and powerful toe off;
• allows foot to naturally stabilize excess pronation.

Additionally, this technology helps the runners to mantain comfortable and efficient running for hours on end.
