Nike Air Max 90 G vs Adidas ZG21

We couldn't find enough data on either option to be able to come to any reliable conclusions. We strongly suggest that you look at some alternatives that also cost around $60.

The Nike Air Max 90 G hasn't managed to get enough recognition from sources that do high-quality hands-on testing and therefore didn't make it into any relevant roundups. That, by itself, makes it difficult to recommend.

As for the Adidas ZG21 - it wasn't considered to be a good enough purchase to earn a spot in any roundups conducted by sources that perform objective hands-on testing, which typically indicates that a product isn't worth its asking price.

As a last step, we wanted to do a head-to-head Nike Air Max 90 G vs. Adidas ZG21 comparison of their review performance but, unfortunately, weren't able to find any review ratings on either product.
