Cushioned Heel System

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

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

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.
