The Women's Gaviota 3 is the premium stability shoe offered by Hoka. They use a "J" shape in the mid-sole to help control the foot from inward roll or over-pronation. This is done by having the the "J" wrap around the heel then stretch underneath the arch. The goal is to offer support without using a stiff media material like many stability shoes of the past. This technology along with the inherent stability of the width and thickness of the Gaviota come to together to create a very stable platform.
