  • Some reports of the liner being difficult to get into, which limits the ease-of-use of this boot.

Expert Reviews

  • Isn’t the warmest on the market for alpine boots, but is warmer than a single boot.
  • Despite being breathable, your feet can get sweaty after wearing these boots for a long time.
  • Since it is such a high-performance boot, the majority of people may not need everything it provides.


The Arc’teryx Acrux AR GTX Mountaineering Boot is a durable, comfortable, and highly weather-protective boot that is suitable for tough conditions. Despite not being the most breathable and fitting pretty narrow for most users, the performance aspects outweigh the negatives. Although many casual users may not need all of the benefits that this boot offers, the easy adjustments, rugged outer layer, and complete weather-proofing make this a tough boot for 3-season use.
