Fast hiking shoe, dynamic and reliable even on the most difficult trails. Rocket DFS GTX adopts the innovative Vibram Traction Lug technology that improves traction and grip by 25 % thanks to the special design. The upper has a crossed rib structure and is protected by a 3D print layer. The exclusive AKU Dual Fit System (DFS) technology, here realized in the version for speed hiking, allows you to vary the degree of precision of the fit by simply acting on the two different lacing systems. It is built with AKU Elica Natural Stride System technology to promote biodynamic efficiency.

ELICA AND THE AKU LAST

The creation of a last is a long and accurate process in which AKU’s long experience in the design and production of high quality footwear is condensed. The identification of the last in relation to the morphology of the foot represents one of the basic criteria in choosing the right shoe.

• The original AKU shape is the matrix, the result of constant research on plantar anatomy. From it, thanks to specific adaptations, the different types of shape and fit derive, which vary in relation to the different models and the specific function of use of the product.

Elica is an integrated system consisting of FORMA – ASSEMBLY INSOLE – MIDSOLE – TREAD that follows the anatomical shape of the sole of the foot and follows the normal inclination of the heel and forefoot. The functional value of the ELICA technology has been certified by specific tests performed at the CERISM Centro Studi Salute laboratories of the University of Verona. The tests show that a more homogeneous distribution of foot pressure during the support and push phases favors comfort by reducing impact and effort during the walk.

• The support phase: During the support phase, the assembly insole is inclined outwards to support the support of the heel. In the external area of the heel the shock-absorbing thickness is greater to absorb impact, while the internal front area of the wedge is made of shock-absorbing material to distribute the thrust force. The asymmetrical design of the tread aligned with the support axis and the protruding profile increase the contact surface.
• The propulsion phase: The assembly insole is inclined inwards to accommodate the support of the forefoot, which naturally rests inwards. The internal front area of the wedge is made of shock-absorbing material to distribute the thrust force and also the tread caps protrude outwards to increase the support surface.

Vibram

Vibram is synonymous with the sole for mountain footwear, an essential component for the safety and technical performance of the product. Vibram’s experience is condensed in the research and development of specific compounds for use on different terrains and environmental conditions; AKU’s contribution is based on the design of the tread profile, conceived and designed according to the intended use of the product. From this synergy are born soles that AKU adopts on many of its models, generating its own exclusive standard of performance.

• The sole design: The sole is one of the elements that make up the shoe and must be considered as part of a single project, consistent with the technical / functional needs of the type of shoe that is being designed and the last on which it will be built. In the case of AKU, the sole must copy the anatomical and helical shape of the bottom of our last, in order to support and enhance its anatomical and dynamic characteristics.
• Another aspect to pay attention to is its reliability which must also be consistent with the use for which the shoe was designed, with a view to minimizing material waste to obtain the maximum required result.
• A further element of attention is the search for the simplicity of interface / assembly between the sole and the other components of the shoe. In summary: maximum attention to the minimalism of the sole, both in weight and in the components and design choices.

GORE - TEX®

• The Gore-Tex® membrane is an exclusive heat-sealed technical fabric which contains about 1.4 billion microscopic pores per square centimeter. These pores are approximately 20,000 times smaller than a drop of water but 700 times bigger than a molecule of moisture vapor. So, whilst water droplets cannot penetrate the GORE -TEX membrane, moisture vapor, namely perspiration in gas form, can easily escape.
