Altra is a professional sports shoe brand founded in Utah, USA in 2009, specializing in long-distance running shoes and off-road shoes. The Altra Ultron brand has a certain number of hardcore fans in the trail running circle.
GoldenHarper, the founder, as an elite runner who completed the marathon at the age of 12 in 2 hours and 45 minutes, understands very well the distress that injuries bring to runners. After graduating from the university of sports injury major, GoldenHarper found that when analyzing running posture for runners, traditional high-drop running shoes will make runners suffer a greater impact when their feet land, and barefoot running will improve running posture to a certain extent. This discovery is the basis for the ZeroDrop sole, the core technology of Altra's running shoes.
Altra's signature technology concepts are: Zero Drop and FootShape.
Zero Drop: It is the leading technology of ALTRA, which means that the thickness of the front of the shoe (midsole + outsole) is designed to be the same as the thickness of the heel, so that the back of the foot and the trunk become more balanced, in order to reduce the load of running on the body, enhance the strength of the Achilles tendon of the foot, provide better power propulsion and guide the runner to form a more scientific running posture and so on.
FootShape: A design that increases the space in the front of the shoe is also defined by ALTRA as a FootShape™ Toe Box, which can be translated literally as: a last design that conforms to the natural orientation of the toes of the foot and continues to be used in subsequent products.
