Wrap Rand

The wrap rand takes the concept of our V2 Rand and develops it further. The rubber surrounds the arch of the foot and supports it in the optimum position for strength and precision.

In most rock boots, the heel is tensioned with a basic single band of rubber, which simply pulls and compresses the heel cup. Boreal have developed a more thorough tensioning system with the Wrap Rand.

A much wider area of the shoe is tensioned, with the strap running all the way under the foot and around the heel. This provides a stable, secure platform for the foot without compromising sensitivity or freedom of movement.

Ref. 11732 SYNERGY
BOREAL Synergy is designed for optimum feel. A highly aggressive last shape is carefully blended with superb sensitivity and supremely sticky BOREAL Zenith Ultra™  rubber to enhance the natural qualities of the foot; a true synergy of design, materials and craftsmanship, enabling you to push your limits on any bloc, both indoor or on rock.
