SPECS

FOOTSHAPE™
Altra's signature FootShape™ comfort gives your feet more space to sit naturally and is designed to address biological differences in men's and women's feet.
BALANCED CUSHIONING™
The Balanced Cushioning™ platform positions your heel and forefoot at an equal distance from the ground, encouraging better alignment and better form.
ALTRA EGO™ MAX
The Altra EGO™ Max midsole foam gives you all the light and luxurious performance with a little extra bounce and added durability.
VIBRAM® LITEBASE
According to Vibram®, Vibram® Litebase outsole reduces 30% of the overall sole weight through a reduction of the sole thickness by 50%, while maintaining Vibram quality in grip, traction, and durability.
BOA® FIT SYSTEM
The PerformFit™ Wrap from the BOA® Fit System is designed to improve directional efficiency and reduce landing impact, while providing a micro-adjustable, precision fit you can change in a matter of seconds.
