Ocun Ozone and Ozone High Volume Gear News

Ozone is a time tested climbing shoe known for its performance on small footholds. 

The greatest support on the smallest footholds

Ozone is designed for performance in every detail. The connection of revolutionary rand construction named 3-Force System, asymmetric shape, sticky toepatch and perfectly fitting heel determines this shoe for use in the hardest routes and boulders.

Thanks to the patented 3-Force System, this climbing shoe is very precise on microfootholds, crimps and also in pockets. The tension in the arch that directs internal forces to the toe, the asymmetrical shape and the 3D midsole guarantee maximum foot support when climbing. The new toe patch allows reliable toe hooking.

Equally reliable, wider fit

HV stands for Higher Volume. Especially for climbers with wider feet or a higher instep, we have developed a high volume last called Asymmetrix Plus. Climbing comfort is also enhanced by the elastic tongue, which fits perfectly around the ankle.

What is 3-Force System

A single piece of rubber encircles the entire volume of the shoe. This is a design solution that ensures precise distribution of internal forces in the climbing shoe. As a result, the shoe has a higher torsional stiffness and fits perfectly. We introduced the 3-Force System in 2009 together with the first model of Ozone.
