FS Quattro

FS Quattro is a unique climbing rubber compound developed Boreal. This compound provides excellent abrasion resistance and consistent performance over a wide temperature range.

FS Quattro rubber is a specific formulation developed by Boreal. It was designed to provide consistent high performance over a wide temperature range, and to offer a long life span. This highly versatile rubber is ideal for all-round rock shoes, with a perfect blend of high friction and durability.


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.
