Altra King MT Aggressive Trail Running Shoe

Altra Footwear releases the Altra King MT, a super aggressive trail shoe.

The Altra King MT features an all-new Altra Ego™ midsole. This proprietary compound provides a bouncier cushioning with more energy return, despite being softer and thinner. This new type of cushion allows a higher responsiveness at a lower weight and has high long-term durability to maintain these properties throughout the life of the shoe.

Underneath that midsole are significant 6.0 mm outsole lugs—the deepest on any Altra shoe—designed for lateral breaking, medial gripping and maximum traction in wet and slippery conditions. The King MT has the most supportive upper of any Altra shoe with TPU overlays and a new feature called FootLock™, a midfoot strap to lock your foot in place on steep descents. A flexible StoneGuard™ rock plate also adds extra underfoot protection from rocks and trail debris.

Altra King MT Trail Running Shoe The King MT features Altra’s lowest stack height at 19 mm and weighs only 8.5 ounces for the men’s sample and 7 ounces for the women’s. This shoe also comes with Altra-specific trail features such as TrailClaw™ metatarsal lugs and a GaiterTrap™ on the heel and a metal loop at the toe for easy pairing with Altra trail gaiters. Color options are black/red, blue, and gray shadow for men, and gray/magenta, black/teal and black for women.

The King MT also includes Altra’s signature FootShape™ toe box and Zero Drop™ platform for a more natural, comfortable fit. The King MT, along with every Altra women’s shoe, is Fit4Her™, which means the women’s model is produced with softer cushioning on a female-specific last to account for the unique anatomical differences between men’s and women’s feet.

Hardrock 100 winner, Jason Schlarb, plans to wear the King MT at his upcoming Coastal Challenge race in Costa Rica. Altra’s OCR team of Andrea Duke, Corinna Coffin as well as Amanda Basham will also wear the King MT as they compete in events across North America.
