Under Armour Sonic 7 Review: A Budget Daily Trainer That Finally Gets Under Armour Back in the Running Game

Introduction

Under Armour has not always been fully committed to the performance running space, but the Sonic 7 changes that. For 2025, the brand brings supercritical foam and a clean, minimalistic design to the daily trainer category, and the result is a shoe that fills a real gap in its lineup. It is not groundbreaking, but at $110 it delivers an excellent performance-to-price ratio, and it is one of the best budget daily trainers to come out in a long time.

Specs and Design

The Sonic 7 is a 26 mm stack height shoe in the heel with an 8 mm drop, giving 18 mm in the forefoot, and it weighs a respectable 9.1 oz (257 g). There is only one material in the midsole: a supercritical foam. No plate, no torsion bar, and no hidden stability elements. It is a very straightforward piece of foam with guide rails on the sides that create a small seat for the foot and some ankle stability, though the foam is soft enough that runners needing real guidance may not find the sidewalls convincing. The heel cup does carry a decent amount of structure without being obtrusive.

The upper is where the minimalist brief really shows. The jacquard upper has no logos and no overlays, giving the shoe a simple, streamlined silhouette that also works well as an incognito casual shoe. Padding along the collar and Achilles flare is restrained but comfortable, and the non-gusseted tongue is a thin piece of soft foam that feels great to the touch. On the outsole, rubber coverage is generous and thick, with cutouts to keep things flexible, though small grooves cut into the rubber can catch tiny bits of gravel on softer surfaces.

How It Runs on the Road

The supercritical foam here is really nice and squishy, and the whole package is very neutral. The setup makes the Sonic 7 great for easy running of about 60 minutes or less. There is a little pace versatility too: the shoe is lightweight, nimble, and not super wide in the footprint, so shorter easy runs with some pace pickup are within reach. It is also a genuinely comfortable casual shoe for everyday wear.

The honest comparison point is the foam in the Nike Rebel line, specifically Rebel version 3. The Hover foam in the Sonic 7 feels a bit more firm and a bit less responsive, without quite as much of that springy decompression. Combined with an upper that is very loose, almost too unstructured, the whole package can feel a little less premium than it looks. It never feels like a flagship shoe, but it does not seem to be trying to be one.

Where It Fits in the Under Armour Lineup

Within the broader Under Armour rotation, the Sonic 7 is the daily trainer, the shoe you reach for on most days for most runs. For faster workouts and racing, the Velocity Elite uses rubberized Flow foam with Pebax and a carbon fiber plate. For slower, more cushioned days, the Infinite Elite uses beaded TPU foam with a tall stack height and extra heel cushioning while keeping the collar from getting too puffy.

Alternatives Worth Considering

Adidas Adizero SL 2

The Adidas Adizero SL 2 is not exactly a budget shoe, but it addresses many of the same boxes. It uses a base of regular Lightstrike, a more standard EVA-type foam, with a small puck of Lightstrike Pro racing foam inside, which elevates the ride into something a lot more fun. Like the Sonic 7, it works best for shorter easy runs or runs with strides, a light tempo, or a light fartlek. The fit and finish is noticeably nicer, and the materials feel better, which is exactly what the Sonic 7 is missing. The styling also looks good both on the run and afterwards. You pay a premium for that, with a price of $130.

Atreyu Daily Trainer

The Atreyu daily trainer delivers the closest overall experience to the Sonic 7. It has a relatively low stack height with supercritical foam that feels almost identical to what is in the Sonic 7, plus an extremely uncomplicated upper with no overlays, gussets, or reinforcements, just a comfortable, well-fitting upper. It works for runs of about an hour or less and comes in at a budget price of $110. One caveat: the original is largely sold out of inventory, but a version two is coming.

Which One Should You Buy?

If you want the best value in a straightforward, neutral daily trainer for shorter easy runs and treadmill sessions, the Sonic 7 is a very easy recommendation at $110. If you can spend a bit more and want nicer fit and finish with a livelier foam blend, the Adizero SL 2 justifies its $130 price. The Atreyu daily trainer remains the closest match to the Sonic 7 experience at the same price, assuming you can find it or wait for version two.

Conclusion

The Sonic 7 is not a groundbreaking shoe, but it is a shoe Under Armour desperately needed: a legitimate, neutral daily trainer with supercritical foam, a clean design, and a price that makes sense. It does not perform quite as well or feel quite as refined as some preferred alternatives, but for runners shopping in the budget category, it is one of the strongest options available today.
