Frequently asked questions
Is Reebok Nano X4 good for Hyrox?
Yes — Nano X4 is one of the most versatile Hyrox training shoes. The 7 mm drop and softer midsole make 8 km of running more comfortable than the Metcon line, and the platform is firm enough for sled and wall balls.
Which is better for sled push?
Nike Metcon 9 has a slight edge for sled push due to its firmer outsole and lower drop. But the Nano X4 is fully capable — most athletes won't notice the difference unless they're sub-75 racers maximising every second.
Can I race Hyrox in Nano X4?
Yes. Many Hyrox racers train and race in the Nano X4 for sub-90 finishes. Faster racers (sub-75) sometimes switch to a dedicated running shoe for race day.
