The Li-Ning LiRen 4 V2 "Black Obsidian" is a popular, low-top basketball shoe known for its excellent performance features and sleek, dark blue/black colorway with blue details. 

Technology and Performance

The shoe is highly regarded for balancing court feel with responsive cushioning, making it a top performer on indoor courts. 

· Cushioning: It features a full-length BOOM midsole, using supercritical foaming technology for a responsive, springy feel and good impact protection.

· Stability and Support: The shoe incorporates PROBAR LOC, a stabilizing carbon fiber or TPU device embedded in the arch to provide support and improve stability during movement. It also has an internal and external heel cage for strong lockdown.

· Traction: The outsole is made with either a solid rubber compound (Tuff RB) or translucent rubber (GCU), with reviewers noting that solid rubber often handles dusty courts better, while both provide great overall grip.

· Fit: The fit is snug; wide-footed players may consider going up a half size. It offers good breathability due to the mesh upper with TPU silk.
