La Sportiva's highest performance summer alpine boot, combining minimal weight, technical excellence on rock and ice, and good hiking comfort. The upper is constructed from light but tough synthetic materials, and includes an integral gaiter for additional protection from snow. The sole combines a carbon fibre stiffening board for rock climbing and crampon support, and an aggressive tread for excellent grip on softer snow and mud.

• Water-repellent high-tenacity nylon 6.6 upper, with abrasion resistant HoneyComb Guard overlay and hidden stitching.
  
• Lightweight PU TechLite rand with rubber toe area.
  
• Waterproof and breathable Gore-Tex Performance Comfort lining.
• Ghilly lacing over forefoot, with no metal eyelets to cause pressure points.
• Steel lacing hooks.
