Lateral Torsion System

At the heart of the Lateral Torsion System is a tensioned band running around the heel and under the instep. This band provides both high levels of support to the foot while standing on smaller holds, and excellent heel fit. However the Lateral Torsion System does not stop there; by utilising thinner rubber in key areas, the flexibility of the shoe can also be enhanced. This combination provides the ultimate balance between support and sensitivity, ideal of any high performance bouldering shoe.

Perfect foot support.

The Lateral Torsion System supports the foot without compromising flexibility.
