Mad Rock - D2.One HV - Climbing Shoes

• Best for:
  • Bouldering
  • Sport climbing
  • Indoor climbing

Why we love it

The D2.One is the most versatile shoe in Mad Rock's Drone family – bridging the stiff power of the Drone 2 and the friction-focused sensitivity of the Drone CS into one hybrid all-rounder. It pairs the CS toe mold with Mad Rock's most adaptable Science Friction rubber, giving you edging power and smearing sensitivity in the same shoe. The patented concave sole drives power transfer through the toe, while the ArchFlex system activates the foot's own muscles for a more secure, efficient platform. The 3D expandable heel adapts to different foot shapes for locked-in heel hooks. This HV version is built for wider feet with taller insteps and larger heels, with a larger elastic over the instep for a more forgiving, dialled-in fit out of the box.
