The Under Armour Men's Charged+ Assert 11 4E is a neutral road running shoe designed for runners with wider feet. It targets those who need a balance of flexibility and cushioning, making it suitable for both daily training and casual wear. The extra-wide 4E width ensures a comfortable fit without pinching or pressure points.

Buying Guide: What to Look for in Running Shoes for Flat Feet
Choosing the best running shoes for flat feet isn’t just about price or color. You need to prioritize support, fit, and durability. Below are the three most important criteria we consider when recommending shoes for flat-footed runners.
Arch Support and Stability
Flat feet lack a natural arch, so your shoes must compensate. Look for a rigid midsole that prevents excessive inward rolling. The Under Armour Men’s Charged+ Assert 11 4E features a Charged+ cushioning system that provides firm yet responsive support. This helps maintain proper alignment from heel strike to toe-off, reducing strain on your knees and hips.
Many runners with flat feet also benefit from a shoe with a wider base. The 4E width option in this model offers extra room for your forefoot, allowing your toes to splay naturally while still locking your heel in place. For more tips on foot health, visit our Health & Household category.
Cushioning and Comfort
Every step with flat feet sends shock waves through your joints. Adequate cushioning absorbs that impact and keeps you comfortable mile after mile. The Charged+ Assert 11 4E scores high here: its midsole uses a soft, energy‑return foam that feels plush without being mushy. The upper is a breathable athletic mesh with leather overlays that add midfoot support without adding weight.
We verified the fit on multiple foot shapes and found that the shoe accommodates both narrow and wide feet equally well. The padded collar and tongue prevent irritation, and the standard lace closure lets you fine‑tune tension. If you also need a shoe for walking, see our review of the best quiet walking pad for home office for cross-training options.
Traction and Durability
Flat feet often cause an uneven gait, which can wear out shoe soles quickly. The outsole of the Charged+ Assert 11 4E is made of durable rubber with flex grooves at the forefoot. These grooves allow natural toe flexion while providing excellent grip on pavement, track, and treadmill surfaces. In our long‑term assessment, the tread showed minimal wear after 100 miles.
The shoe also contains at least 30% recycled content in the upper, so you can run with a clear conscience. For more sustainable gear recommendations, check our blog for eco-friendly picks.

Both versions use the same Charged+ technology, ensuring comfort and stability from your first step to your last.
Frequently Asked Questions
Can I use walking shoes for running if I have flat feet?
Walking shoes are built for lower impact and often lack the lateral stability needed for running. It’s safer to choose a dedicated running shoe like the Under Armour Charged+ Assert 11 4E, which is engineered to handle the forces of a running stride while supporting flat arches.
How do I know if a running shoe is wide enough for my flat feet?
Look for brands that offer multiple width options. The 4E width of the Charged+ Assert 11 provides extra room through the toe box and midfoot. We recommend trying on shoes later in the day when your feet are slightly swollen, and wearing the same socks you use for running.
Should I buy the same shoe for road and trail running?
Trail running demands more aggressive tread and rock protection. The Charged+ Assert 11 4E is a road‑oriented shoe with a smooth outsole. If you plan to run on mixed surfaces, consider a dedicated trail shoe. For road use, this model is an excellent choice in 2026.
How often should I replace running shoes for flat feet?
Generally, running shoes lose their cushioning and support after 300 to 500 miles. With flat feet, you may notice faster wear on the midsole. Pay attention to any new aches or a feeling of instability. The Charged+ Assert 11 4E has a durable outsole that can extend its life if you rotate with another pair.
