If you went gaga over the Air Max 1 ACG pack we previewed recently, you’ll flip to hear that Nike is smacking the ACG treatment on the Air Max 90. While the silhouette remains untouched, the classic runner gets a complete outdoors upgrade with tough weatherproof materials and a mean steely look. The mostly grey paneling is contrasted against popping purple, coral and white accents, as well as alternate blue and yellow speckled laces. For those who like to tackle tough terrain in maximum freshness. Dropping early 2011.
