Reebok just planted its flag in competitive fitness, signing on as the official footwear and apparel partner for Xenom London later this month. Every athlete in the field gets a co-branded technical tee and judges and volunteers get Nano training shoes. Even Xenom founder Keith Barlow says he’ll be racing in the Nano X5 himself.

On its own, this seems like a standard event sponsorship but in context, it’s the third major shoe brand in twelve months to make a real bet on hybrid racing.

Where Things Stand

Puma has owned the HYROX footwear conversation for years now as the event’s longtime apparel and footwear partner. Smart.

Nike missed the boat but last week did announce its own line of hybrid-fitness shoes that wont go on sale until October and April 2027. Stupid.

Now Reebok is in, attaching itself to Xenom’s “decathlon of fitness” format instead of going head-to-head with Puma on HYROX turf. Smart.

And we don’t blame them. Xenom is young and only ran its first event this past June in Dallas — but it showed up with backing ($15 million from Jeffrey Katzenberg’s WndrCo) and impressive numbers at the starting line, with nearly 400 athletes, $75,000 in prize money, and sponsors like Rogue, Gatorade and Yeti already on board.

For a brand like Reebok that’s spent the last few years searching for relevance outside of CrossFit, it’s an emerging format without an entrenched footwear partner.

What It Means for Athletes

We’ve said it before: the hybrid athlete is the fastest-growing customer in the sport, and the shoe companies know it. The SOS memo finally hit their desks and when three of the biggest names in performance footwear are actively competing for space at the start line of events like these, you best expect a whole slew of new shoes are coming.

More R&D dollars aimed at compromise-shoe design (stable enough to lift in, light enough to run fast in) means better options are coming, faster, whether you’re doing HYROX, Xenom, or your own local event that is stitched together on a Saturday.

It also tells you something about where the sport is heading. Brand money doesn’t chase hobbies; it chases categories that are about to get a lot bigger. Reebok, Puma and Nike aren’t hedging here. They’re positioning.

We’ll be watching whether Reebok’s Xenom bet stays London-only or turns into the kind of multi-event partnership Puma has built with HYROX. Either way, if you’re training for a hybrid race this fall, expect your shoe options to get more confusing, even if long term that means better.
