The Theory is an indoor climbing shoe designed to perfectly adapt to the shapes of footholds and volumes of indoor climbing. The maximum sensitivity and high dynamics allow unique adaptability at the edges, making the shoe perfect for indoor use. The basis for the creation of the theory is a study by La Sportiva's R&D department on the gripping behavior of gorillas and the sensitivity of cats' paws, combined with the findings of the new climbing routes in the halls, which are characterized by very wide volumes and extremely dynamic movements. This shoe is designed to develop the maximum of strength and dexterity while maintaining the highest sensitivity on every type of. New construction with exclusive D-Tech™ technology (Dynamic Technology): the sole wraps the side of the shoe to make the side edges disappear, ensuring dynamic traction and adaptability to the shapes of the most modern indoor grips. The sole made of a Vibram® The rubber tip covers 90% of the front surface of the shaft to provide support when toehooking while providing adaptability to different foot shapes. Thanks to its high adaptability, the entire construction of the shoe makes it easier to apply pressure to the volumes of modern indoor route setting as well as to provide support when cross-kicking. The upper Velcro fastener allows for optimal tension regulation. Theory: climbing species evolution!
