Nike Air Max 90 SI

The Air Max 90 SIs are one of Nike's lower-mid priced men's sneaker offerings. Nike promotes these casual sneakers as having a 1990s design aesthetic mixed with the technology of today. Like other sneakers in the Air Max line, the Air Max 90 SIs have Max Air technology in the heel.

This technology absorbs the impact of repetitive motion (which can be straining even with everyday activity), and protects the foot from potential injury. The mesh upper of these sneakers is reinforced with overlays, so that the fit will be comfortable and breathable. Nike's PU midsole is promoted as the most dense, durable and stable material available for midsoles. This midsole is full-length. The waffle pattern on the rubber outsole will help provide traction.
