The Li-Ning Speed 12 "Temper" is a specific player-exclusive (PE) colorway of the Li-Ning Speed 12 basketball shoe, endorsed by NBA player Fred VanVleet. It is known for its responsive, low-profile design ideal for quick guards. 

Design and Aesthetics

· Colorway: The "Temper" edition predominantly features white uppers, though the exact accents and details are specific to this PE version.

· Signature Details: It is part of the Fred VanVleet collection within the Speed 12 line, featuring unique branding and design elements associated with the player.

· Aesthetics: The entire Speed 12 line is designed with a sleek, modern look that emphasizes a low-to-the-ground feel and agility on the court. 

Performance and Technology

The Li-Ning Speed 12 is highly rated by guards and players who rely on speed and sharp movements. 

· Traction: The shoe features Li-Ning's GCU (Ground Control System) outsole, known for its very strong, tacky grip on various court surfaces. Reviewers note it performs well on dusty courts with occasional wiping and produces a loud "squeak" (indicating excellent grip).

· Cushioning: It uses full-length Li-Ning Boom technology (supercritical foam), which provides significant weight reduction, improved rebound performance, and enhanced cushioning compared to traditional materials.

· Stability & Lockdown: The shoe offers great containment and a secure lockdown fit, including substantial padding around the ankle and heel collars. It incorporates a PROBAR LOC stabilizer for anti-torsion support and wide, flared outriggers for stability during hard cuts and quick lateral movements.

· Upper: The upper uses a SOLID SYSTEM of compression and support, combining synthetic leather, fabric, textile, and TPU materials for a balance of breathability and structure.
