UPPER - NEW ENGINEERED MESH
Durable engineered mesh. A new, lightweight mesh designed specifically for road shoes that protects the foot while providing excellent breathability. It has been updated with thinner mesh for a more secure, comfortable fit and increased flexibility.

MIDSOLE - ALTRA EGO™
Responsive, bouncy, energy-efficient, and fun to run on—that is Altra's renowned midsole technology. Unlike typical midsoles made with EVA foam, Ego has been tested for durability in extreme weather conditions and offers a soft, comfortable feel with excellent energy return.

FOOTSHAPE™ TOE BOX
A wide toe box that follows the natural shape of the foot—it really is that simple. The design provides ample space in the forefoot for toes to spread naturally with every stride, without squeezing them together. It offers stability and promotes a midfoot strike.
.

.
BALANCED CUSHIONING
Zero drop, with the forefoot and heel at the same height—the best position for your foot
The level forefoot and heel design feels like standing barefoot in shoes, avoiding unnatural foot positioning and promoting a midfoot strike, which is the most sustainable running form.
INNER FLEX™
This technology features a flexible, grid-like midsole design that allows runners to place their feet as desired without adding unnecessary weight or removing essential impact protection from the midsole.
