The Nike WMNS Air Classic BW basically is the first Air Max, renamed only. The short form BW stands for "Big Window".
This sneaker was significant for the modern classic sneaker as it's Air-Unit-Technology and the rearward transparent part was revolutionary.

This Nike WMNS Air Classic BW "White/Persian Violet-Black" comes this time in a original colorway in smooth fabric in a White/Persian Violet-Black colorway. Features a great color combination, a nice white mesh toebox and is in the meantime a highly anticipated re-issue!
Simple and clean colorway for everyday.
