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