The Altra Paradigm 4 is completely updated and revamped with an Altra EGO™ midsole for plush cushion and ultimate energy return; a knit upper for durability, and integrated Stabilipods for enhanced support. The same sweet GuideRail™ system is still here to help steer a tired or pronating foot, and with the addition of Altra EGO™ in the midsole and knit in the upper, this shoe is even more resilient, comfortable and cushioned than before.

FOOTSHAPE™ TOE BOX
Allows your toes to relax and spread out naturally for more comfort and stability in uphill climbs and downhill descents.
BALANCED CUSHIONING™ PLATFORM
Places your heel and forefoot the same distance from the ground to encourage proper, low-impact form throughout your trail run.
Grid-like grooves in the midsole allow your foot to flex while being lighter, for more speed and better performance.
An outsole technology that actually maps the bones and tendons of your foot to help it bend and move naturally.
Dual-Nature midsole compound with a responsive, yet soft feel for increased energy return.
A feature found on our dynamic support shoes that acts like a highway guide rail to provide guidance only when you need it.
Acts as a stabilizing tripod by enhancing the three natural stability zones in your foot to help prevent excessive foot collapse or pronation.
