Evaluation of Arc'teryx Acrux SL Mountaineering Boots
The Arc'teryx Acrux SL is a top-tier approach shoe designed for hiking and climbing in challenging alpine environments. This shoe, crafted by the renowned outdoor brand Arc'teryx, offers a unique blend of comfort, durability, and performance that makes it a favourite among climbers.
The Acrux SL is ideal for climbers who frequently walk short distances to the crag. With a focus on comfort and durability, shoes like the La Sportiva Boulder X or Scarpa Crux might seem heavy in comparison. The Acrux SL, on the other hand, boasts a low profile and narrow toe box, making it perfect for those who prioritise agility and precision on the rock.
One of the standout features of the Acrux SL is its seamless nylon upper, which provides exceptional durability against abrasion and crack wear. This feature, combined with a patch of smooth "climbing zone" rubber under the big toe, stiff edges, and a durable upper material, ensures excellent smearing on wet rock and edging performance.
However, the Acrux SL is not without its drawbacks. Its Vibram sole, while providing excellent traction on various terrains, can struggle on wet leaves or in mud. Additionally, due to its high price tag and sleek appearance, it may be overkill in some environments, making it less suitable as an all-rounder.
Wide-footed climbers may also want to look for an alternative, as the Acrux SL does not accommodate wide feet. It is recommended to size down 2/3 of a size or try them on before buying to ensure a comfortable fit.
The Acrux SL is one of the more expensive approach shoes on the market, with prices ranging from $170 to pricier leather and GTX versions. However, its competitive climbing performance, particularly when compared to models like the Five Ten Guide Tennie and Scarpa Gecko, justifies the investment for many climbers.
The rubber used in the Acrux SL is Vibram Megagrip, which offers superb grip on rock, although it is slightly less sticky than Stealth rubber on the Five Ten Guide Tennies. The shoe also features shallow lugs and heel tread for traction and braking, ensuring excellent performance on various terrains.
The Acrux SL is made in 2/3 size increments on the European scale, providing a wide range of sizes for climbers. Despite not being waterproof, it has a high degree of water resistance due to its seamless nylon upper and moisture-wicking adaptive liner.
The shoe's upper provides stability and protection, keeping dirt and debris out over long hikes. The adaptive liner adds a climbing slipper-like snugness for extra stability on technical rock. Additionally, the Acrux SL offers a supportive ride, balancing lightweight construction with stability for long hikes with heavy packs.
The Arc'teryx Acrux SL was tested in the Chaltén Massif, showcasing its exceptional performance in challenging alpine environments. Whether you're a seasoned climber or a beginner, the Acrux SL is a reliable choice for those seeking a high-performance approach shoe.
