AKU Croda Boa GTX Black/Orange

AKU Croda BOA Gore-Tex (AK957) – Black/Orange

The AKU Croda BOA Gore-Tex. 770g. BOA Li2 dual-rotor dial closure — micro-adjustable fit on technical terrain, with gloves on, without stopping. Gore-Tex More Seasons, Vibram Litebase Croda outsole, Double Density PU midsole, 6–4mm Nylon and 30% Carbon Fibre lasting board for torsional rigidity under load. Rubber rand for precision edge contact. Integrated water-repellent gaiter for snow and debris protection. A technical mountaineering boot where the BOA closure is not a convenience feature — it is a precision tool for managing fit across the full range of approach terrain and alpine conditions.

WHY YOU'LL LIKE IT

• BOA Li2 dual-rotor closure — two independent bidirectional dials for separate heel and forefoot tension control; adjust on the move in crampons or with gloves on, tighten for technical descent without unlacing, open for the approach descent without sitting down
• 6–4mm Nylon + 30% Carbon Fibre lasting board (Stiff) — torsional rigidity across the full board, consistent with the Croda DFS EVO GTX; holds its shape under load on technical ground, provides the underfoot precision that approach terrain and exposed ridges demand
• Vibram Litebase Croda outsole — the Croda compound provides grip and precision on technical rock surfaces; Litebase construction reduces sole weight while maintaining the friction and durability profile needed for mountain approach and alpine use
• 770g — 40g heavier than the Croda DFS EVO GTX (730g) — the BOA Li2 dual-rotor system accounts for the weight difference over the DFS lace-based variant; otherwise sharing the same lasting board specification, Gore-Tex More Seasons lining, and Vibram Litebase outsole
• UK 3.5–13 including half sizes

BEST FOR

• Technical mountaineers and alpine walkers on three-season terrain who want BOA dial precision for managing fit under load — on the approach, at the crux, and on the descent without stopping to relace
• Scramblers and ridge walkers on exposed UK mountain terrain where the rubber rand and stiff Nylon-Carbon Fibre board deliver underfoot precision that a softer boot cannot match
• Climbers and alpinists who regularly adjust footwear tension across changing terrain and conditions, and for whom glove-compatible closure is a functional requirement rather than a preference
