Li-Ning MIX sports shoes are composed of three separate parts: flexible skeleton-framework, integrated out-midsole, inner boot. The three components are interlocked with each other utilizing the construction of “SUN-MAO”, which is inspired from Chinese traditional furniture and buildings. This assembly way is environment-friendly and stable. And it helps to disassemble, exchange and recombine rapidly, which brings great enjoyment to consumers by creating their own MIX. The inner boots can be worn indoor separately. Moreover, MIX makes it possible to only discard worn parts and keep others to reduce unnecessary wastes.
