Boreal - Joker Wmns - Light Blue/White - Climbing Shoes

• Best for:
  • Indoor climbing
  • Bouldering
  • Sport climbing

Why we love it

The Joker Wmns stays on your feet for an entire session without making you count the minutes until you can take it off. The split leather and breathable microfibre upper moulds to the foot over time, while the double hook-and-loop straps let you dial in the fit quickly between burns. The IRS sole construction resists deformation and keeps rubber contact consistent long after lesser shoes would have lost their grip.

Features

• FS-Quattro Rubber: Boreal's proven rubber compound delivering the optimum balance of grip, abrasion resistance and hardness – with the unique property of maintaining consistent performance across temperature changes.
• IRS – Integrated Rand System: A one-piece climbing sole that never deforms and prevents delamination over time. Allows different rubber thicknesses across the sole in a single construction, improving fit precision and long-term durability.
• CHS – Cushioned Heel System: A cavity in the moulded heel filled with shock-absorbing EVA, cushioning the foot on hard landings and adding comfort between routes.
• Strong pre-tensioning: Heel tension keeps the shoe locked to the foot for a secure, performance-oriented fit – particularly effective on steep terrain and overhangs.
