Boreal Joker

Comfortable, versatile climbing shoe
Boreal Joker Boreal Joker  ()

Description

The Joker features a super-comfortable semi-asymmetric last with slimmer fitting heel and low tension rand. An upper of high quality split leather and synthetic microfibre with a quick and simple strap closure is combined with a PU Air Net lining for exceptional comfort and a fresh new look.

The 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. Joker is superbly versatile. Size normally for all-day comfort on long routes and extended sessions; size down for higher performance.

Integral Rand System (IRS)
The innovative one-piece sole and rand construction of the Integrated Rand System (IRS) allows Boreal to finely tune the rubber thickness around the shoe for the optimum balance of fit, performance and durability. By combining the rand and sole unit into one piece, there is zero chance of delaminating.

Cushioned Heel System(CHS)
When climbing all day, normal rock boots become tiring very quickly as the thin, sensitive nature of their construction does little to protect the foot. With the Boreal Cushioned Heel System (CHS) an EVA shock absorbing insert under the heel cushions and protects the foot with no loss of climbing performance. This means that walking between routes and stepping off the rock onto hard, uneven surfaces can be achieved in comfort.

Zenith
Zenith rubber is a high performance rubber developed by Boreal. Zenith is designed for no-compromise performance, and features incredible friction properties combined with an ability to hold micro edges. This ultimate compound is featured on our highest performance rock shoe models.
