La Sportiva Akyra II GORE-TEX Trail Running Shoes
The Akyra II GORE-TEX is the perfect shoe for moving quickly and easily on any trail, even in the most challenging weather conditions. The KPU 3D Grid construction and Impact Brake System ensure stability and support, while the Trail Rocker combined with the comfortable and flexible fit add energy to every step.
GORE-TEX Upper
The upper of the Akyra II has been made with a breathable mesh that provides a constant flow of air whilst built-up heat escapes, keeping feet cool and comfortable throughout use. A GORE-TEX membrane in the upper ensures the boots are durably waterproof combined with optimised breathability offering enduring weather protection. Water stays on the outside while perspiration can easily escape from the inside, thanks to their non-insulated construction they are the ideal solution for people who value outstanding climate comfort and heat release. The shoes use a 3-layer upper construction for comfort and breathability, the stability is provided by the KPU 3D Grid, which is a cage-like structure that prevents excess movement, keeping your foot in an upright position and reducing the risk of injury. A traditional lacing system completes the upper, reducing in-shoe movement for distraction-free strides.
Injection Moulded EVA Midsole
The Akyra II GORE-TEX from La Sportiva uses an Injection Moulded EVA midsole that differs from the standard compression moulded EVA midsoles for a high degree of cushioning and better elasticity of the compound. These features assist the propulsion phase of the gait cycle, making these shoes ideal for use on off-road trails. Furthermore, EVA-injected midsoles drastically reduce the squash effect of the EVA over time, allowing the compound to maintain the same characteristics and high performance for its entire duration. La Sportiva has also included an Ortholite Hybrid, a 5mm hiking insole constructed using 20% recycled materials, to provide instant comfort when you put them on. Encouraging a more natural heel-to-toe transition, and a smooth gait cycle, the shoes feature La Sportiva's Trail Rocker system.
FriXion XT Outsole
The outsole developed by La Sportiva uses the FirXion XT tread with an impact brake system. The exclusive design features a trail rocker technology that promotes natural outer heel and inner toe support of the foot when running. The dual rubber outsole perfectly balances grip, durability and shock absorption to deliver comfort, stability and support while you clock up the miles. The stable base will give you a good platform to help prevent injuries on unpredictable terrain while the Impact Brake System enhances traction to give a more assured footing uphill and downhill.
