Boreal have been manufacturing high end mountaineering boots for almost 40 years and the Arwa Bi-Flex represents the very latest advances in design and materials creating a versatile mountain boot which is lighter, warmer, more comfortable and better to climb in than you would have been thought possible back in 1975.
The Arwa Bi-Flex is ideally suited to Scottish winter climbing, cascade ice, technical alpinism and 4000m peaks.
Boreal sponsored climber Nick Bullock has selected Arwa as his boots of choice for ice and mixed recently. Nick has chosen Arwa for a number of breakthrough routes at the extreme end of Scottish winter climbs including some notable first ascents on routes such as Cold Revenge IX/8 on Slime Wall, Buachaille Etive Mor.
Light: The upper of the Arwa is manufactured from lightweight Dynatec and Lorica synthetic textiles giving a substantial weight saving over traditional leathers. The weight saving is further enhanced with an ultra-light yet rigid advanced carbon fibre composite midsole.
Warm: Arwa uses a 200gsm single layer Thinsulate® lining to surround the whole foot giving an excellent warmth to weight ratio. Unlike on other boots this Thinsulate® layers also extends under the foot which dramatically reduces heat loss through conduction to the ground.
Comfortable: Our Bi-Flex system allows for natural freedom of movement at the ankle and greatly improves the comfort. A three-layer tongue provides plenty of padding against pressure points and adds some useful adjustment.
Technical: Arwa is fully compatible with automatic (step-in) crampons. Dual density TPU crampon attachment lugs (hard at the back and soft at the front) ensure a positive fit for the rear heel clip, whilst adding extra shock absorption at the front bail which is particularly noticeable when front-pointing on hard ice.
Arwa Bi-Flex is available in sizes 6-14 U.K.
Arwa Bi-Flex Women’s fit is available in sizes 4 ½ - 8 U.K.
