The GEL-QUANTUM 360™ 6 RE trainer is made to keep your mind and body in motion. Using the GEL-QUANTUM 360™ 6 trainer as its foundation, this version is updated for everyday comfort and functionality. The MONO-SOCK™ construction from the GEL-NOOSA™ TRI series was instrumental for developing the shoe's upper. This creates a snug fit that's easy to slip on and off. Keeping the GEL-QUANTUM 360™ 6 tooling intact, this shoe provides advanced cushioning that's geared for all-day comfort.
