Back in 2019, I got my first pair of Reebok Nanos, the Nano 9, and was so impressed with the shoe’s durability and versatility, it ended up cracking that year’s GP100.

While I was late to the party — the original Nano launched in 2011, hot on the heels of Reebok signing a 10-year deal with the CrossFit Games — that particular iteration was a standout, thanks in part to a two-piece outsole that boosted its run-ability.

Though that shoe could handle short bursts of speed, it definitely wasn’t equipped for longer runs, as I learned first-hand after wearing my pair for a three-miler in a pinch.

That experience pointed up a major problem with gym footwear for those of us who favor wide-ranging CrossFit and HIIT style workouts: You can wear something that flexes enough to run well or something that’s firm enough to support big lifts, but getting both features in one shoe is rare.

According to the marketing, from front to back, the X5’s midsole foam actually shifts from running shoe-responsiveness to lifting-shoe stability. That’s just catnip for people demanding more versatility from their gym shoes. Big if true, as they say.

Now, as the Nano heads toward its 15th anniversary, the CrossFit Games is far in the rearview mirror, but that quandary remains. Can the just-announced Nano X5 solve it? Based on what we know so far, that certainly seems to be one of its primary ambitions.

Born to run?

The Nano has long possessed stability in the sole that makes it perfect for plyometrics and big, explosive lifts. So the real challenge is making it somehow also flexible enough to really run.

Toward that end, check out the first two bullet points Reebok touts in promoting the X5:

DUALRESPONSE EVA Midsole offers zoned durometer foam that is cushioned and more responsive in the forefoot, while firmer and more stable in the rear.

Decoupled Metasplit Outsole creates enhanced flexibility and runnability.

A few big, made-up sounding words there, but the meaning is still pretty clear. The first point indicates that from front to back, the midsole foam itself actually shifts from running shoe-responsiveness to lifting-shoe stability.

That’s just catnip for people demanding more versatility from their gym shoes. Big if true, as they say.

As for the second point, I’ve seen versions of that language dating back to at least the Nano 9. It’s not all that new, but together with the first point, it does augur well for this sneaker being a respectable runner.

Rounding out the highlighted updates of this 15th-anniversary edition are a “performance comfort collar” for a locked-in fit, a Flexweave upper offering breathability, a 7mm drop and a weight of 12 ounces.

Reebok just sent an X5 sample my way, so stay tuned for an update on whether it really is the run-ready gym shoe we’ve always wanted.

Availability and pricing

The Reebok Nano X5 will be available on January 24th for $140+. It will be offered in various unisex and women’s launch colorways with additional pack drops throughout the season.
