Our signature FootShape™ comfort gives your feet more space to sit naturally and is designed to address biological differences in men's and women's feet.
Our Balanced Cushioning™ platform positions your heel and forefoot at an equal distance from the ground, encouraging better alignment, better form, and a low impact landing.
Our Quantic™ foam offers a luxurious and lightweight cushioned midsole, designed for miles and miles of comfort.
Our grippy MaxTrac™ outsole provides the perfect combination of grip, traction, and durability on all types of terrain.
These canted lugs on the outsole are strategically placed beneath the metatarsals to provide added traction underfoot.
This hook-and-loop tab allows our strapless gaiter to easily attach to the shoe, adding protection against rocks and debris.
These grid-like grooves in the midsole are designed to provide flexibility and movement.
FootShape™ Toe Box - Embrace The Space
Traditional running shoes feature pointy toe boxes that squeeze the toes out of their natural position –increasing risk of bunions, hammertoes and plantar fasciitis. Altra’s FootShape™ toe box allows the toes to relax and spread out naturally and the big toe to remain in a straight position. This enhances stability and creates a powerful toe-off to maximize running performance. We wish we could call it some scientific breakthrough, but we’re simply giving your foot the working space it needs.
Benefits of FootShape™ Toe Box
- Keeps big toe straight for greater stability and a more powerful toe-off
- Allows toes to relax and spread out naturally
- Allows foot to naturally stabilize excess pronation
Zero Drop™ Platform
Every Altra running shoe features a fully cushioned Zero Drop™ platform that places the heel and forefoot at the same distance from the ground. This natural balance aligns the feet, back and body posture for less impact. It also strengthens the Achilles and lower calf muscles that have been weakened over a lifetime of running on elevated heels.
Benefits of Zero Drop™
- Heel and forefoot are the same distance from the ground
- Promotes proper form to reduce initial impact by 3–5 times
- Natural Achilles loading for better propulsion
- 1-to-1 ratio naturally aligns feet, back and body posture
- Encourages better running technique
- Weight-balanced from front to back
Not Like the Others – For Good Reason
Altra’s complete line of Zero Drop™ footwear separates us from most running shoe companies that feature shoes with elevated heels. Running in elevated heels removes the foot from its natural position and encourages high-impact over striding.
Innovation at 300°
After countless customers entered his family running store complaining of pain and injury, Altra founder Golden Harper felt compelled to develop a solution. His college research on running injuries, combined with video analysis of running technique, made it easy to see that the design of traditional running shoes promoted poor form and excessive impact. Using a toaster oven, he began to melt the outsoles of customers’ shoes and carve out unnecessary heel cushioning. It was ugly, but it worked! Harper coined the term “Zero Drop™” to describe the level cushioning and perfect weight balance from heel to forefoot. Runners immediately felt the difference. It was their results and running success that fueled the creation of Altra Running.
Altra Running is the only running shoe company to provide a complete line of fully cushioned Zero Drop™ running shoes. Our lightweight blend of EVA and A-Bound™ cushioning runs evenly from heel to toe and is weight balanced from front to back to encourage proper low-impact running technique.
