Under Armour Women's Charged Assert 9 Running Shoe - Lightweight 10mm

Our review of the Under Armour Women's Charged Assert 9 finds it best suited for road runners and walkers who prioritize breathable comfort and responsive cushioning. The single biggest reason to buy is the Charged Cushioning midsole, which delivers a springy, durable ride without adding unnecessary weight. Throughout testing the shoe felt stable at the midfoot, comfortably padded around the collar, and noticeably breathable thanks to the engineered mesh upper, making it an easy daily trainer for short to medium distances.

Key Features

• Engineered mesh upper: Provides exceptional breathability and a lightweight feel while giving targeted support where the foot needs it most.
• Durable leather overlays: Lock in the midfoot for added stability during quick direction changes and regular use.
• Charged Cushioning midsole: Uses compression molded foam to offer responsive energy return and long-term durability under repeated impact.
• EVA sockliner: Molds to the foot for a soft, step-in comfort and extra heel padding at initial contact.
• Solid rubber outsole: Covers high impact zones to improve longevity and maintain traction with a tire-inspired flex pattern.

Who It's For

The Charged Assert 9 works well for women who run primarily on roads or use a trainer for daily walking, gym sessions, or light runs and want a breathable, lightweight shoe with a comfortable ride. It is also a good pick for those who need a stable midfoot and modest cushioning without a bulky platform.

Runners seeking maximal cushioning for long ultras, trail runners who need aggressive off-road traction, or those requiring a very narrow race fit should look elsewhere; some users report a roomier toe box and mixed feedback on long-term durability.
