THE SHAPE

The creation of a last, the result of constant research into plantar anatomy, is a long and accurate process in which AKU's long experience in the design and production of high-quality mountaineering, backpacking and trekking footwear is condensed.

The original AKU shape is the matrix from which, thanks to specific adaptations, the different types of shape derive, which vary in relation to the different models and the specific function of use of the product.

Soft and welcoming shapes are the prerogative of the footwear in the ACTIVE segment, intended for light outdoor activities, in non-demanding conditions and on regular surfaces. Enveloping and anatomical shapes are instead intended for the footwear in the TREKKING segment, to offer stability and promote dynamic action when walking on mountain paths with very irregular surfaces. Finally, dry and elongated shapes are used in the professional footwear in the MOUNTAIN segment, to promote precision and sensitivity when used in rock and ice climbing.

The different fits:

  • PERFORMANCE-PASSFORM

    Slim and enveloping shapes for professional footwear in the Mountain segment, designed to promote precision and sensitivity when used when climbing on rock and ice. The heel has an anatomical shape designed to hold the foot and with the forefoot part which, without compromising precision at the toe, is more spacious and thus guarantees better warmth and blood circulation even during prolonged stops with the feet in the snow.

  • ANATOMISCHE PASSFORM

    Comfortable and enveloping anatomical shapes for footwear in the Trekking segment, designed to offer comfort and stability and to promote dynamic action when walking on mountain paths with uneven surfaces.

  • PRÄZISE PASSFORM

    Precise and slightly curved shapes for footwear in the Backpacking and Multiterrain segments, suitable for dynamic use on medium difficulty terrain or challenging terrain on technical terrain.

  • FRAUENPASSFORM

    Shapes specifically developed for the female footbed anatomy, comfortable and enveloping, provide comfort and stability when walking on mountain paths with uneven surfaces.

  • ENTSPANNTE PASSFORM

    Soft and welcoming shapes for footwear in the Mountain Inspired segment, intended for free time and light outdoor activities.
