Get the Theory here. Theory is the indoor performance climbing shoe designed for perfect adaptation to the new forms of indoor-climbing holds. The shoe’s extreme sensitivity combined to high dynamism, allows for unprecedented spreadability on holds making it particularly suitable for use in the gym. Theory derives from the study carried out by La Sportiva’s R&D department on gorilla prehensile skills and the sensitivity of feline fingertips, combining the evolutionary analysis of the new climbing routes in indoor gyms characterised by very large volumes and extremely dynamic movements. Starring: La sportiva athlete Jacopo Larcher & La Sportiva climbing product manager Luca Gabrielli.
