Two interesting new Nike Tier Zero releases are coming up next month. The Grid Pack consists of the Air Max 90 CT TZ and the Air Max 90 Flywire TZ. Both come in very lightweight fabrics, a silver grid pattern on the upper and a hybrid sole.

The pack will be released at Nort Berlin on April 17th.

More detailed images of the Nike Air Max 90 CT TZ and the Air Max 90 Flywire TZ follow after the jump.
