The Li-Ning Sharp Blade 4 V2 "Roland" (also known as the Li-Ning LiRen 4 V2 Roland) is a professional basketball shoe, not a badminton racquet. It is a low-top sneaker praised for its excellent traction and responsive cushioning.

Key Features and Technology

Cushioning: The midsole is equipped with Li-Ning's Boom cushioning technology and a mesh stroble board, which offers excellent energy return and shock absorption. Reviewers note it is designed for bounce and responsiveness rather than plush softness.

Traction: The shoe features a durable rubber or translucent outsole with a multi-directional tread pattern, providing superior grip and anti-slip performance on various courts, including both indoor and outdoor surfaces.

Support & Stability: It incorporates a PROBAR LOC stabilizing device in the arch, connecting the forefoot and heel to provide robust support and prevent excessive twisting during quick movements.

Upper Material: The upper combines textile and TPU (thermoplastic polyurethane) materials, offering a balance of support, breathability, and durability.

Fit & Comfort: The shoe has a secure lacing system and a padded collar for a locked-in feel. Reviewers generally recommend going true to size, with wide-foot individuals potentially needing to go half a size up.
