Best for
Mizuno's Sky Prime is a premium cushioned trainer whose softness comes from Foam Wave construction, which combines multiple midsole materials into one max-cushion platform. It is neutral, with no stability features, and 295 g is a fair weight for how much softness is under you.
It suits you if you want a soft, protective shoe for easy days and long runs on the road, where comfort matters more than pace. Recovery mileage and long slow efforts are its best use.
It is not a speed shoe, and it is not a lightweight. With max cushioning, it will not give you a snappy feel for workouts or racing, and you pay a premium for softness more than for versatility.
