Under Armour Charged Assert 9 Running Shoe - Lightweight (Style Z4RC)

Our review of the Under Armour Charged Assert 9 running shoe finds it best suited for neutral road runners who want a lightweight, responsive daily trainer without paying premium prices. The single biggest reason to consider these shoes is the Charged Cushioning midsole, which uses compression molded foam to deliver a springy, durable feel underfoot that helps absorb impact on easy and tempo runs. Breathable mesh and leather overlays combine to keep feet cool while providing midfoot lockdown for predictable stability.

Key Features

• Lightweight mesh upper: A 3-color digital print mesh delivers full breathability so feet stay cool on longer runs.
• Durable leather overlays: Leather pieces lock in the midfoot to provide structure and help prevent unwanted slippage.
• EVA sockliner: The soft sockliner gives comfortable step-in cushioning for daily training and casual wear.
• Charged Cushioning midsole: Compression molded foam offers responsive energy return while maintaining durability over many miles.
• Solid rubber outsole: Rubber coverage on high impact zones increases durability without adding excess weight.

Who It's For

These shoes are a good match for neutral runners who want a lightweight, well-cushioned road shoe for daily runs, gym sessions, and casual wear. Runners who prioritize a breathable upper, moderate stability from leather overlays, and a 10mm offset will likely appreciate the balance of cushioning and responsiveness.

Runners seeking maximal stability for overpronation, ultra-distance cushioning for extremely long runs, or premium race-day flats should look elsewhere. Also, shoppers who require a very narrow or extremely wide fit may need to try them on due to mixed sizing feedback.

Pros & Cons

Pros
