The Women's Superior 3.0 has been discontinued. It was replaced by the Altra Superior 4.0.
Outland USA says:
When it comes to product feedback, Altra hears you loud and clear! That is why the award-winning Superior trail shoe is back, with a few changes, just for you. With accurate sizing, a stronger upper for durability, and a small lateral flare on the outsole for added stability, this update takes your perfect trail shoe to a whole new level. The Superior 3.0 also has a fresh new pattern and features Fit4Her technology, so you can hit the trails with stamina and style. And the Superior 3.0 comes with the trail-specific features you love: a TrailClaw outsole, StoneGuard rock protection, and GaiterTrap technology so that you can have the ultimate trail advantage.
Historic Range: $49.48-$110.00
