    I do like them overall, but do I like them better than Nano 7s? Hands down, they are way better than Nano 7s.

  • 90 / 100 by BarBend • Jake Boly • Level 2 expert

    I liked the changes Reebok made to this model compared to the 7 (which wasn’t my favorite whatsoever), and the newly constructed bootie. It’s a shoe I can both workout in and wear in my day-to-day with comfort.
