TECHNOLOGIES:

Cushioned Heel System

Boreal developed the 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.

Integrated Rand System

The IRS system goes a step further in the manufacturing of climbing shoes. 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.

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.
