Features

• A newly developed Zenith Quattro outsole includes a specially shaped heel cavity filled with shock absorbing EVA for improved under foot cushioning
• The medium stiffness midsole paired with the sticky and durable Zenith Quattro rubber provides the ideal blend of edging support and long-lasting friction
• Incredibly comfortable 3D Air Net lined shoe for long routes or long training sessions
  
• Fit in your street shoe size to wear all day or in smaller sizes for increased precision
• Usage: Climbing courses, training (indoor and outdoor) and long routes

• Zenith is a unique high performance climbing rubber developed by Boreal. This compound provides outstanding friction and excellent hold on small edges.
  

Integrated Rand System

• The IRS system goes a step further in the manufacturing of climbing shoes. This one piece climbing site never deforms and has a superior fit. Boreal can achieve different thicknesses in the rubber and the one-piece construction increases durability.
  

Cushioned Heel System

• In order to improve comfort when stepping off the rock of walking between routes, Boreal developed the Cushioned Heel System. Using shock absorbing EVA under the heel, the foot is cushioned from rocky and hard ground.
