Per Nike: The LEBRON 11 Gamma Blue highlights a new approach to containment, support and natural motion; created in a shade of blue representing unbreakable strength.
The Gamma Blue inspiration is based around tempered steel. At high heat, steel develops an oxide layer that's blue in color. After being forged, steel is treated again to create an unbreakable resistance similar to LeBron's style of play on the court.
The LEBRON 11 Gamma Blue colorway represents superior integrity, optimal strength and strong impact resistance. The Gamma Blue plated panels of the Nike Hyperposite technology shields the foot for defense. A smooth Swoosh represents the tempered steel spectrum, from yellow to the distinctive blue.
