Currently, the spotlight is on Li-Ning's lightweight carbon shoes. These shoes incorporate carbon fiber and are positioned as training carbon shoes within the Li-Ning lineup. They offer good responsiveness and are relatively easy to handle, making them recommended for beginner racers as well. ~Size Feeling~ Chinese size 250, which is approximately 25.5~26.0cm. ~Mileage~ I've run about 100km in them, and they still feel almost new. This is my second pair, and I'm selling them because I bought a new third pair in a different color. ⬇️For Reference Basic Specifications • Model Name: Li-Ning FEIDIAN 5 Challenger • Weight: Information suggests approximately under 200g (around US8.5). • Midsole/Plate Construction & Material: According to reviews, lightweight and responsive materials such as "BOOM Fiber" upper and "Light Bullet/BOOM series midsole" are used. • Upper: Described as lightweight mesh + "BOOM Fiber" material. • Outsole: The brand's unique "GCR" or "GCR LOC/GCR Rubber" is introduced. • Usage: There are articles that introduce them not only for speed/racing purposes but also as "racing trainers/for speed training."
