Questions answered
FAQ
Is the Cloud X good for the gym?
Yes, it is one of the better shoes for gym versatility. The stable platform handles weight training, the cushioning works for cardio, and the Speedboard adds responsiveness for explosive movements.
Can you run in the Cloud X?
For short to moderate runs, yes. For dedicated long-distance running, a purpose-built running shoe like the Cloudswift or Cloudsurfer would be better. The Cloud X is a cross-trainer first.
How does the Cloud X compare to the Cloud 6?
The Cloud X has a wider, more stable platform for lateral movements and training. The Cloud 6 is lighter and more focused on running. Choose the X for gym and training versatility, the 6 for running.
Does the Cloud X run true to size?
True to size but narrow, consistent with On Running. Half size up for wider feet.
Is the Cloud X good for everyday wear?
Yes, the moderate cushioning and clean design make it work well as a daily shoe. Lighter and less bulky than most cross-trainers.
