The Testarossa is one of La Sportiva's more aggressive climbing shoe designed with hard boulders and overhung sport routes in mind. Its highly asymmetric downturn's developed to grip overhung jugs, tiptoe micro-edges, and work through blank sections with technical precision. It's one of the first climbing shoes to pair a stiff toe box with a flexible arch for better agility on steep and vertical climbs alike. La Sportive redesigned the heel for a snugger fit that feels more secure on heel hooks.
