361° Biospeed BB "Duckyo" — Supercritical Speed for the Perimeter Game

The 361° Biospeed BB "Duckyo" (672511115-1) is a professional-level low-top basketball shoe that fuses flagship supercritical performance technology with a playful Duckyo character collaboration. Released as part of the 2025 performance line, it is engineered for shifty guards who demand a running-shoe-like transition with elite court grip.

Performance Technology

  • Elite Cushioning: Full-length QU!KCQTECH (CQT) supercritical foam midsole — exceptionally soft and bouncy with up to 75% energy return for explosive, fatigue-free play.
  • Propulsion System: Integrated QU!KBONE carbon-fiber plate enhances torsional rigidity and delivers snappy forward propulsion during takeoff.
  • Superior Traction: Rigid Polyurethane (RPU) outsole — a technology typically reserved for elite running shoes — provides crispy multi-directional grip on both clean and dusty courts.
  • Lightweight Build: One of the lightest in its class at approximately 300g (US 8.5), reducing fatigue during high-speed transitions.

Design & Aesthetic

  • Colorway: Vibrant Yellow and White with character-specific Duckyo branding on the tongue and heel, inspired by the iconic chubby white duck character.
  • Silhouette: Low-cut design for maximum ankle mobility and quick lateral shifts.
