CAN THE CLOUD X 4 BE USED FOR RUNNING?
Yes, it can handle short runs and cardio sessions, but it’s primarily designed as a training shoe rather than a long-distance running shoe.

Most runners report a true-to-size fit with a snug midfoot and secure heel hold.
WHAT’S THE BEST WAY TO MAKE SURE IT FITS COMFORTABLY?
Measure your feet at the end of the day and leave about a thumb’s width of space in the toe box. Make sure the heel feels secure and the midfoot is comfortably snug.
