The Li-Ning Speed 10 'White Gold Black' are professional basketball shoes known for their lightweight design, excellent cushioning, and strong stability, making them a popular choice for guards. They are not badminton shoes as the query might imply. 

Key Features and Technology

The shoes incorporate several of Li-Ning's proprietary technologies to enhance performance: 

LI-NING BOOM Technology: The full-length midsole uses an innovative, supercritical fluid foaming process that makes it significantly lighter, improves rebound performance, and offers a longer service life compared to traditional materials.

PROBAR LOC: A stabilizing device embedded in the arch connects the forefoot and heel, providing crucial support and protection for the arch during movement, which improves overall stability.

SOLID SYSTEM: An adjustable shoelace loop device allows for customized tightness of the upper loop, enhancing the fit and comfort of the shoe.

Upper Material: The upper is constructed from a combination of textile and TPU, designed with a high-density double mesh for enhanced ventilation and support.

Outsole: The outsole is made of TUFF RB rubber, which is durable and designed for both indoor and outdoor court use, providing reliable grip and slip resistance.

Design: Reviewers note they are low to the ground for better court feel and quick push-offs, ideal for speedy and shifty players.
