The Boreal Joker Lace 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 secure lace closure is combined with a PU Air Net lining for exceptional comfort and a fresh new look. A newly developed Zenith Quattro outsole now includes a specially shaped heel cavity filled with shock absorbing EVA for improved under foot cushioning.

The medium stiffness midsole combines with the sticky and durable Zenith Quattro rubber to provide the ideal blend of edging support and long-lasting friction. From starting out, to long routes, all day wear, performance training and bouldering, no pack is complete without a pair of Joker Lace.
