Under Armour HOVR vs Charged: Foam Technology

Understanding the two foams

HOVR and Charged are Under Armour's two primary midsole foams. Each represents a different philosophy in cushioning design, and knowing how they differ helps you choose a sneaker that matches your intended use. HOVR is positioned as a high-energy-return foam with a connected core that aims to reduce impact and return energy with every step. Charged is a more traditional responsive foam, engineered to provide a firm, springy feel that keeps you in touch with the ground.

Both foams appear across Under Armour's running, training, and lifestyle sneakers, but they serve distinct purposes. The choice between them often comes down to how much cushioning and energy return you want versus how much ground feedback you need. Some runners prefer a plush, protective ride for long miles, while others need a more direct, connected sensation for speed work or gym sessions. Understanding the trade-offs is the first step in making an informed decision.

For a full look at Under Armour's lineup, see our best Under Armour sneakers guide, which covers models that use both foams.

Energy return: the HOVR advantage

Energy return refers to how much of the impact energy you put into the ground is given back to you as you push off. A foam with high energy return can make each step feel less tiring, especially over long distances. HOVR's key feature is its emphasis on this property. The foam is built around a proprietary energy web that works with the midsole to reduce energy loss, helping you maintain a consistent stride and feel less fatigued on longer runs.

Charged also returns energy, but it does so with a firmer, more direct response. It doesn't aim to give you the same plush, high-rebound sensation that HOVR does. Instead, it focuses on returning energy in a way that feels more immediate and controlled. This can be beneficial for short, quick efforts where you want a snappy push-off without extra sink or squish.

If you prioritize energy return as a cushioning trait, HOVR is the more obvious choice. Many of Under Armour's daily trainers and long-distance models use HOVR to provide that soft, propulsive feel.

Ground feel: Charged's edge

Ground feel is the sensation of the surface underfoot. A firmer foam like Charged transmits more of the ground's texture to your foot, which can be helpful for agility, balance, and quick adjustments. This is why Charged is common in training shoes, cross-training shoes, and some speed-oriented running models. When you need to feel the floor for lifting, jumping, or cutting, a softer, more isolated foam can actually hold you back.

HOVR, by contrast, isolates you from the ground with its softer, more cushioned platform. That can be a positive for recovery runs and easy miles, as it reduces the impact on your joints. However, it can reduce proprioception, the sense of where your body is in space, which is important for navigating uneven terrain or making precise movements. For activities where ground feedback is critical, Charged's firmer ride gives you a clearer picture of the surface.

If ground feel matters more than softness, look for shoes with Charged in our best running sneakers guide. Those models tend to have a lower, more responsive profile that lets you feel the road or track beneath you.

HOVR vs Charged at a glance

The table below summarizes the main differences between the two foams. Keep in mind that these are general tendencies; the actual feel can vary depending on the specific shoe model, stack height, and outsole design. Still, it gives you a quick reference when comparing sneakers.

How to choose between HOVR and Charged

Start by considering your primary activity. If you run long distances and want a comfortable, energy-returning shoe that protects your joints, HOVR is a strong option. It can be a good pick for daily training and walking as well, especially if you prefer a plush, forgiving feel. HOVR's softness also helps reduce impact stress, which is valuable for beginners or those returning from injury.

If you do speed work, HIIT, or lift weights, Charged's firmer, more responsive foam gives you better stability and ground connection. It also works well for shorter runs where you want a snappier, more efficient toe-off. For gym sessions, a firmer base helps you feel the floor and maintain proper form, especially during squats, lunges, and other strength exercises.

You can also mix both: some sneakers combine HOVR and Charged in a single midsole, giving you a cushioned heel and a firmer forefoot. That hybrid approach can offer the best of both worlds, providing impact absorption where you need it most and a responsive toe-off where you push off. If you want a single shoe for varied activities, look for models that blend the two foams.

Beyond running: walking and daily wear

HOVR's soft, high-rebound foam makes it a good choice for walking shoes, as it offers all-day comfort and impact absorption. If you stand for long periods, HOVR can help keep your feet from feeling tired, and its cushioning may reduce strain on your knees and lower back. Many walking shoes from Under Armour use HOVR to provide a smooth, supportive ride.

Charged is often found in training shoes that need a more secure, grounded feel. For lifestyle and casual wear, either foam can work, but the ground feel difference matters if you're on uneven surfaces or if you prefer a firmer, more minimal shoe. Some people find Charged more stable for everyday errands because it has less squish, allowing for a more natural walking motion.

Durability and break-in

Foam longevity is another factor to weigh. HOVR's dense construction tends to hold up well over many miles, but its softness can compress over time, reducing energy return as the foam breaks down. Charged, being firmer, often maintains its shape longer and may show less visible wear, though it can feel harsher as the miles add up if the midsole hardens with age.

Break-in periods also differ. HOVR often feels comfortable right out of the box, with minimal break-in needed. Charged may feel stiff initially and can take a few runs or training sessions to soften slightly and adapt to your foot. That doesn't mean one is better; it just means you should be prepared for a slightly different initial experience.

To maximize the lifespan of either foam, rotate between two pairs if you run frequently. This gives the foam time to recover its shape between workouts. For more on when to replace your sneakers, see our guide on when to replace.

What to pick for your use

Questions

Which foam is better for marathon training?

HOVR, because its high energy return can help reduce fatigue over long distances and its soft cushioning absorbs impact.

Can I use Charged for daily walking?

Yes, but you'll feel more of the ground; if you prefer a softer walk, HOVR is more comfortable.

Do Under Armour shoes mix both foams?

Some models combine HOVR and Charged to offer a balance of cushioning and responsiveness, often with Charged in the heel or forefoot.

Does HOVR or Charged last longer?

Charged, being firmer, often retains its shape longer, while HOVR's softness may compress over time. Rotating shoes can extend the life of either.
