Ozone HV Climbing Shoes – Precision Edging for Wide Feet

Elite performance, now with a fit designed for wider feet.

The Ozone HV brings the renowned performance of the original Ozone to climbers who need a higher volume fit. Built on the Asymetrix Plus last, this version delivers the same cutting-edge precision, edging power, and technical design — now with a more spacious toebox and wider overall fit for greater comfort and support.

Built for Big Moves on Small Edges

Whether you’re sending vertical crimp lines or tackling steep overhangs, the Ozone HV offers reliable stability and performance thanks to its patented 3-Force System. Power is channelled precisely to the toe, allowing you to stand confidently on even the tiniest footholds.

Key Features:

  • 3-Force System (Patented) – Distributes pressure for maximum torsional stiffness and balanced foot placement.

  • 3D Fit Midsole – Anatomically shaped for strong toe support and edging performance.

  • Sticky Toe Patch – Improves friction and control on toe-hooks and scums.

  • Wider Last & Bulkier Toebox – Offers a comfortable, secure fit for climbers with normal to wide feet.

  • Arch and Heel Pretensioning – Delivers a snug, high-performance fit while transferring power efficiently to the toe.

  • Microfibre Upper – Lightweight, breathable, and 100% vegan.

  • Vibram Sole (4mm) – Trusted grip for both indoor walls and outdoor rock.

Perfect for Wide-Footed Climbers

The Ozone HV is tailored for climbers with wider feet or those who prefer a roomier toe box without sacrificing performance.
Have narrower feet? Check out the standard Ozone, built on the same high-performance platform with a slimmer, more aggressive fit.

FAQ

How do I choose the right climbing shoe for my foot?

Choosing the right climbing shoe starts with knowing your foot shape (Egyptian, Roman, or Greek) and foot type (narrow, regular, or wide). Each model is built differently—with unique shapes, tension systems, and stiffness levels—designed to suit specific foot profiles and climbing needs. For example, wider feet may fit better in models like the Ozone HV or Bullit, while narrow feet suit the Fury or Sigma. Matching the shoe to your foot ensures better performance and comfort.

What are the different types of rubber used in Ocun shoes?

Ocún uses three types of high-performance rubber in their climbing shoes, each designed for different needs and skill levels:

  • CAT rubber μ 1.1 – High friction & durable

This compound offers a good balance of grip and durability. It’s designed for beginner models, focusing on abrasion resistance while still providing reliable friction for both rock and indoor climbing.

  • CAT rubber μ 1.5 – Super sticky & precise

This is Ocún’s super sticky rubber, engineered for maximum grip and precision. It enhances friction between the sole and the surface, even on tiny footholds and edges. It’s used in mid-range to high-performance shoes and is great for technical climbing.

  • VIBRAM XS Grip – Sticky + stiff

This trusted Vibram compound blends stickiness with stiffness, making it excellent for demanding routes that require precision and stability on small edges. It’s used on shoes designed for advanced and performance-focused climbers.

What is CAT rubber?

CAT (Climbing Adhesion Technology) rubber is a high-performance climbing rubber developed by Ocún to deliver exceptional grip on rock and indoor surfaces. Its effectiveness is measured using the μ (mu) friction coefficient, which shows how well the rubber resists slipping when pressure is applied.

To measure this, Ocún uses a custom test that simulates real climbing conditions—pressing the rubber onto a surface with a known force and measuring how much it resists sliding.

CAT rubber starts at a μ value of 1.1, with higher numbers meaning more friction:

  • μ ≤ 0.9: Standard rubber
  • μ = 1.1 – 1.4: High friction rubber
  • μ ≥ 1.5: Super sticky rubber

CAT rubber bonds to the surface through macro-scale grip (rubber sticking to rough rock texture) and micro-scale adhesion (rubber molecules interacting with the surface), giving climbers reliable traction even in demanding conditions.

What are lasts and why are there so many different ones?

A "last" is the mold that shapes a climbing shoe—it defines the fit, profile, and performance. Because no two feet (or climbs) are the same, different lasts are created to match various foot shapes, climbing styles, and comfort needs. For example, some are built for narrow feet and precise edging, while others offer more volume and all-day comfort. More lasts = better fit for more climbers

You can check the full range of lasts and how they differ here.

What is 3FS?

The patented 3 Force System (3FS) used in the Ozone, Ozone HV and Fury provides precise pressure distribution contributing to a higher torsional stiffness and resulting in perfect balance on the tiniest footholds and edges.

In short it ensures no rotation on the foot, better stability, and great support on small footholds

What’s the difference between 2D and 3D midsoles in climbing shoes?

The midsole affects how a climbing shoe balances support and sensitivity. 3D midsoles are anatomically shaped to match the human foot, offering better toe support and power transfer. They come in different stiffness levels, from 3D Fit Hard (more support, less sensitivity) to 3D Fit Middle (a balance of both).

2D midsoles are flatter and come in varying stiffness too, like 2D Toe Soft for maximum sensitivity, or 2D Fit Hard for more structured support.

Choosing the right one depends on whether you prioritise feeling the rock (sensitivity) or edging power (hardness).

That's a lot to take in... is there a simple way to compare all the shoes?

Absolutely. We’ve wrapped up all the key info—models, fits, midsoles, lasts, and more—into one clean, scroll-stopping chart. Whether you’re chasing performance or prioritising comfort, it’s the quickest way to line up your options and find the perfect match without getting buried in the details.
