The sole must copy the anatomical and helical shape of the bottom of the AKU lasts, in order to support and enhance their anatomical and dynamic characteristics.
Other aspects to pay attention to are: reliability, which must be consistent with the use for which the shoe was designed and with a view to minimising material waste, and the search for simplicity of interface/assembly between the sole and the other components of the shoe.

The Megagrip compound

A special compound designed by Vibram® to offer excellent grip on dry and wet surfaces.

Vibram Arctic Grip is Vibram's most advanced system for ensuring grip even during the winter season. Specifically designed for slippery and icy surfaces.

Vibram N-OIL

The Vibram N-OIL compound is another innovative solution from Vibram®, designed to offer a green alternative in the world of footwear. It's made with over 90% natural ingredients, while maintaining the performance and quality of Vibram. This compound is also produced without the use of solvents or chemicals. This represents a step forward for AKU and Vibram® in their constant pursuit of innovation and high-performance, responsible products. AKU uses the N-OIL compound on some of its environmentally responsible models.

Traction Lug

New design focused on the key element of traction. Vibram® has developed the tread with lug-shaped micro-features, increasing the contact surface with the ground by 50%. Vibram® thus guarantees up to 25% better traction and improved stability during use. AKU has chosen to use this technology in footwear that requires high performance and improved grip, especially during push-off.
