Under Armour Charged Assert 9 Running Shoe - Lightweight (Style ZC4K)

In this review of the Under Armour Charged Assert 9 running shoe the bottom line is clear: this is a dependable neutral trainer for runners who value lightweight breathability paired with responsive cushioning. The shoe's mesh upper and EVA sockliner make it comfortable from the first step, while the Charged Cushioning midsole provides a lively, protective ride that suits daily runs and road workouts. It is best for runners seeking a balance of flexibility and cushioning without extra bulk.

Key Features

• Lightweight mesh upper: The three-color digital print mesh provides full breathability so feet stay cool on longer runs.
• Durable leather overlays: Leather overlays lock the midfoot in place to add stability during turnouts and quick reps.
• EVA sockliner: The soft EVA sockliner delivers immediate, comfortable step-in cushioning that reduces break-in time.
• Charged Cushioning midsole: Compression molded foam offers responsive energy return and durability for repeated training sessions.
• Solid rubber outsole: Rubber covers high impact zones to increase durability while keeping overall weight down.

Who It's For

The Charged Assert 9 is best for neutral road runners who want a lightweight, versatile trainer for daily miles, recovery runs, and tempo efforts. Runners who prefer a modest 10mm offset and a balance of flexibility and cushioning will appreciate how the shoe moves with the foot.

Runners who need maximal motion control, heavy support for severe overpronation, or thick maximal cushioning may want to look elsewhere. Also, those needing specialized racing flats or trail protection should choose a model designed specifically for those purposes.
