The Tonale GTX not only convinces with its fashionable look, the technical innovations are in the foreground: a stretch zone is integrated in the heel area of the cuff of the Tonale GTX. Thanks to this Heelcuff Freeflex system, the entire cuff is more elastic. It fits snugly, but is still absolutely pressure-free. The variofix® system ensures a perfect fit and heel fixation. The free running Speed wire pulls evenly tight around the heel when lacing in. The Vibram® rubber profile sole with EVA Duo Density cushioning wedge also provides a secure grip and thanks to GORE-TEX the shoe is guaranteed waterproof.
