How to Clean Under Armour Charged Cushioning

What is Under Armour Charged cushioning?

Under Armour Charged cushioning is a proprietary foam blend used in many of the brand's athletic sneakers. It is designed to provide a balance of softness and responsiveness, making it suitable for running, training, and everyday wear. Because the foam is exposed on the midsole, it collects dust, dirt, and grime over time.

Keep in mind that this article focuses on cleaning the midsole itself, not the upper or the outsole. For a complete cleaning routine for the whole shoe, see our guide on cleaning sneakers.

Why gentle cleaning matters

The foam in Charged cushioning is engineered to compress and rebound with each step. Harsh detergents, bleach, or abrasive brushes can break down the foam's cell structure, reducing its shock absorption and shortening the shoe's lifespan. The same care applies to other foam midsoles like EVA vs TPU or adidas Boost.

Proper drying is equally important. Leaving shoes damp in a warm environment can encourage microbial growth, which leads to odor. The National Institute for Occupational Safety and Health (NIOSH) emphasizes the importance of keeping materials dry to prevent mold and mildew in workplaces; the same logic applies to your footwear. Always dry Charged foam thoroughly, but avoid direct sunlight or radiator heat, which can cause the foam to warp.

Step-by-step cleaning process

Follow these steps to clean your Under Armour Charged midsoles without causing damage.

Start by removing loose dirt. Tap the shoes together or use a soft-bristled brush or dry cloth to wipe off surface dust and pebbles. This prevents scratching during the wet cleaning step.

• Mix a small amount of mild liquid dish soap or sneaker cleaner with lukewarm water. Avoid hot water, which can soften the foam excessively.
• Dip a soft cloth or a soft-bristled brush (an old toothbrush works well) into the solution and gently scrub the Charged foam in circular motions. Focus on stained areas but do not press hard.
• Rinse the cloth or brush in clean water and wipe away any soap residue from the midsole. Repeat until no suds remain.
• For stubborn scuff marks, use a white vinyl eraser or a mixture of baking soda and water applied with a cotton swab. Rinse after treating.
• Never immerse the entire shoe in water or use a pressure washer. Excess water can get into the foam and compromise its structure.

Drying methods that protect the foam

Drying is as important as the cleaning itself. After cleaning, gently press a dry towel against the midsole to absorb excess water. Do not wring or twist the shoe.

Allow the shoes to air dry at room temperature in a well-ventilated area, away from direct heat sources. Placing them near a fan speeds the process without thermal stress. Never use a clothes dryer, heater, or hairdryer, as high heat can cause the foam to soften and lose its shape.

For faster drying, stuff the shoes with crumpled newspaper or paper towels to absorb moisture from the inside. Replace the stuffing until the shoes are fully dry. This method is also covered in our guide on drying sneakers quickly.

Check the midsole for any remaining moisture before wearing. If you store damp shoes, you risk microbial growth and foul odors. Once fully dry, the foam should return to its original density.

Addressing odors in Charged foam

Odors often develop when moisture and bacteria become trapped in the foam. After cleaning and drying, you can treat the midsole with a light spray of white vinegar diluted with water (one part vinegar to three parts water). This neutralizes alkaline odors without leaving a strong smell once dry.

If odors persist, consider replacing the insoles. The sock liner can harbor bacteria even when the foam is clean. Our guide on deodorizing sneakers provides additional methods. For fresh footwear routines, also see sneaker rotation needs to give each pair time to dry between uses.

Preventive care for long-lasting foam

Protect your Charged cushioning before it gets dirty. Wipe the midsoles with a dry cloth after each wear, especially in wet or dusty conditions. If you anticipate heavy use, consider applying a water-repellent protector designed for foam materials; this creates a barrier that makes cleaning easier.

Store your sneakers in a cool, dry place away from direct sunlight. Ultraviolet rays can degrade the foam and cause discoloration. Also, avoid leaving them in a hot car, as elevated temperatures can permanently set the foam. For more storage tips, see our guide on storing sneakers.

Regular upkeep not only keeps your sneakers looking good but also preserves the performance of the cushioning system. If you notice the foam feeling flat or compacted, it may be time to replace your sneakers. Our article on when to replace sneakers can help you assess the condition.

What to pick for your use

Questions

Can I use bleach to clean Under Armour Charged cushioning?

No. Bleach is too harsh for the foam. It will break down the polymer structure, reducing cushioning and discoloring the midsole. Stick to mild soap and water.

Is it safe to put Under Armour sneakers in the washing machine?

Not recommended. Machine washing can agitate the foam, compress it, and cause water penetration. Hand cleaning is safer for preserving the Charged cushioning.

How often should I clean the midsoles?

Wipe them after every wear if they are visibly dirty. A deeper cleaning can be done once a month or when you notice buildup. Avoid over-cleaning, which can strip natural oils from the foam.

Can I use a hair dryer to speed up drying?

No. High heat from a hair dryer can deform the foam and cause it to soften or lose shape. Air drying with a fan is the safest option.

Will vinegar damage the Charged foam?

Diluted white vinegar (1 part vinegar to 3 parts water) is mild and safe. It won't harm the foam when rinsed off. Use it sparingly for odor removal.

How can I prevent white midsole discoloration?

Keep shoes away from direct sunlight and store them in a cool, dry place. After cleaning, dry them thoroughly. A light protective spray can also reduce staining.
