Li-Ning Men's FEIDIAN 5 CHALLENGER Racing Running Shoes SUPER BOOM Cushion CARBON-FIBER PLATE LiNing Sneaker ARMV001 ARMW003

The shoes are remarkably lightweight — most reviews mention weights around 198–225 g. Sizing aligns with European standards, though some buyers recommend going half a size up for a more comfortable fit. The packaging includes cardboard insoles and often includes a gift — an elastic exercise band or tape. The shoes work well for interval runs, tempo runs, and long distances, though they excel at higher speeds.

Critical reviews are rare (only 2.9% negative ratings). Some buyers note a slightly stiffer feel compared to ultra-soft models, but most see this as an advantage — the shoe is responsive, not soft. One buyer mentioned mild heel discomfort during walking, though not while running. The insole is glued down and difficult to remove, which may be an issue for those wanting to use a custom insole.
