How, you many be asking, is Altra going to make the very much loved Timp 1.5 better? By making it a whole ounce lighter, more flexible and with a smoother ride. THATS how! The full length Quantic midsole update results in a softer, lighter and more resilient underfoot ride. The deep flex grooves in the midsole reduce weight but also contribute to a shoe that is more flexible, despite being a max cushion shoe. And don’t think they’ve skimped on the outsole – the grippy MaxTrac outsole digs its multidirectional teeth into almost any surface the trail throws your way.


Quantic is a lightweight midsole technology that provides plush comfort with a responsive ride
Inner Flex flex grooves system provides additional flexibility and cuts weight for increased performance
Natural Ride System (NRS) includes a more natural, foot-shaped last and zero drop to assist in proper foot mechanics and more natural foot movement
Foot Shape Toe Box allows the shoe to move with the bones and tendons of the foot


MaxTrac Outsole uses anatomically-shaped sticky rubber that prioritizes grip and durability on uneven terrain


Open Mesh creates a durable upper that provides optimal protection from trail debris
TPU Overlay provides lightweight structure to secure fit around the top of the foot
Gaiter Trap System allows for Altra Gaiter to stop debris from building up beneath the shoe (sold separately)
