The Mizuno Sky Prime, a max cushion running shoe, offers a smooth ride for long, slow efforts, according to reviewers. The shoe features a dual-density midsole with Enerzy NXT Plus foam for responsiveness and Enerzy NXT EVA foam for stability. Despite its comfort, reviewers noted the shoe's weight and limited color options.

Reviewers praised the Sky Prime's comfort and stability during long runs, with one tester completing a 20-mile run without discomfort. The shoe's wide platform and breathable mesh upper contributed to its comfort. However, some found the shoe too heavy and lacking in versatility compared to other max cushion shoes.

While the Sky Prime excels in providing a smooth, cushioned ride for easy miles, its high price and limited features may deter some runners. The shoe's design caters specifically to long, slow cruising, which may not appeal to those seeking a more versatile training shoe. Related: Allswifit ActiveRise Plus: Budget-Friendly Tempo Shoe.
