Believe in the Run published a review of the Mizuno Sky Prime on October 12, 2026, based on testing by three reviewers over 20 miles. The shoe is a plateless max-cushion trainer with a 47mm heel and 41mm forefoot stack, a 6mm drop, Enerzy NXT and Enerzy NXT Plus foam, and a 10.7 oz weight in a US M9. Reviewers found it stable and comfortable over long easy miles, but heavy, limited to slow paces, and priced at $200. This is the only report in the current coverage, so no conflicting figures or earlier claims are available to compare.
