This technology of the Hoka One One brand is able to guarantee dynamic stability, which intervenes to offer support when and where it is needed. The J-Frame technology exploits the functional characteristics of the Active Foot Frame midsole. The J-shaped insert intervenes extending to the back of the sole, giving lateral support to the heel.

This system designed by Hoka engineers, guides the foot providing the right stability, without resorting to rigid and heavy materials.
