- Infinitoo: Exclusive technology that absorbs negative impacts on the ground and guarantees an energy return never seen before, all this together with the Rock-Guard Skin external protective layer. The Infinitoo midsole maintains its original elasticity characteristics over time.

- OrthoLite Mountain Running (5 mm insole): Allows greater perspiration and high comfort thanks to the plantar ventilation, favors the elimination of sweat while keeping the foot dry, allows a longer duration in time thanks to a technology that prevents excessive compression of the material and has washable antibacterial treatment for greater hygiene.

- FriXion Red: La Sportiva FriXion sole compounds were created in order to create a contact zone with different waterproofing and durability parameters depending on the type of use and the ground on which La Sportiva footwear is used. The Fricion Red Dual Mix Compound outsole offers an optimal combination of grip, wear resistance and shock absorption. It is used in versatile dual compound soles.

- Impact Brake System Innovative system that absorbs impact, increases traction and improves retention during braking. Conceived and developed by La Sportiva.
