Altra SUPERIOR 4 USA
If you already loved the Superior, you are in for a treat. The Superior 4 is even lighter, grippier and sleeker. It features a knit, wrap-around style upper to more security, plush yet resilient Altra Quantic™ midsole and sticky MaxTrac™ rubber outsole. The rounded heel style and updated lug pattern tops off this light weight trail crusher.
Benefits
BALANCED CUSHIONING
Places your heel and forefoot the same distance from the ground to encourage proper, low-impact form throughout your run.
FOOTSHAPE™ TOE BOX
Allows your toes to relax and spread out naturally for more comfort and stability.
FIT4HER™
The Fit4Her™ technology means we customize every women's shoe to the unique anatomy of the female foot.
INNERFLEX™
Grid-like grooves in the midsole allow your foot to flex while being lighter, for more speed and better performance.
GAITERTRAP™
Hook-and-loop tab allows strapless gaiter attachment that prevents debris from building up beneath the shoe.
TRAILCLAW™
Canted lugs positioned strategically beneath the metatarsals to provide traction at toe off.
MAXTRAC™
A perfect combination of grip, traction and durability that will eat up gnarly terrain like a boss.
QUANTIC
Quantic™ was inspired by a desire to combine the plush feel of Altra EGO™ with a lightweight ride, it cushions every step and floats over any surface
