HA-1 Run


Product Description

Product Description

The HA-1 run with built in a-Fit technology provides anatomically correct support and fit for the left and right foot.
  • The HA-1’s functional support and unique knitting technology stabilizes the heel in a neutral position and lifts up the arch of the foot to prevent it from leaning inward.
  • This will reduce the stress from repetitive impact on the foot to reduce plantar fasciitis.
  • Flyweight fabrication reduces weight, while V-tech technology enhances ventilation for a comfortable fit.
