Cross-training shoes occupy an awkward middle ground โ too cushioned for the lifters who want ground feel, too stiff for the runners who want turnover, too generic for anyone who takes either discipline seriously.
On built its reputation on running, but it has spent the last several years trying to convince gym-goers that its CloudTec sole translates to the weight room. The Cloud X 4 was the most credible attempt yet. But it left many serious trainers cold, and the reasons weren’t subtle.

Durability complaints surfaced early.ย Run Repeat’s testers noted the outsole wore down faster than expected,ย especially given the $160 price point. Cushioning was also dinged as feeling inconsistent underfoot, particularly during lateral movements.
Traction on gym floors also drew criticism. For a shoe asking cross-trainers to treat it as an everyday workhorse, those were compounding failures, not minor quibbles.
The newย On Cloud X 5, which has quietly been on sale in On stories for weeks now but only recently became available for online purchase, is On’s answer to that criticism.
A chance at redemption

On reworked the outsole rubber compound and extended coverage across high-wear zones to address the X 4’s outsole breakdown under lateral load.
