Great shoes
Size: 12 X-Wide
Color: (001) Black/Black/White
Under Armour shoes are simply good, comfortable, supportive, and great for everyday wear. The cushioning feels solid without being too soft, and the fit is snug in all the right places. Whether I’m walking, running errands, or getting a light workout in, they stay comfortable and hold up well. The build quality feels durable, and the design looks sharp without being flashy. If you want dependable shoes that perform well and feel great straight out of the box, Under Armour is always a reliable choice.

Give them a try - you will not be disappointed!
Size: 13
Color: (100) Mod Gray/Mod Gray/White
Great shoes - no doubt about it. It was time for some new sneakers and after perusing the plethora of choices out there I saw these. They looked kind of cool, not too overly colored and appeared comfortable. Usually I prefer to shop locally and try shoes on before I buy, but I gave these a try. All I can say is Under Armour did a great job, the fit was perfect and I will be buying more!

Very good, but not great
Size: 11.5
Color: (102) Mod Gray/Mod Gray/White
These are good shoes, not great, but excellent value for the price point. I ran a 5K in them after only wearing them once and they were comfortable. Not super comfortable, but comfortable enough. I was a little worried at first because they felt a bit stiff, but no issues. If your'e looking for a decent pair of shoes for running, walking, or working out without breaking the bank, these should work.

My New Go-To Shoe
Size: 10.5
Color: (600) Red/Red/Black
After trying a lot of different running and training shoes over the years, the Charged Assert 10 has moved straight to the top of my list. The red colorway looks sharp—bright enough to stand out without being loud, and it’s held up well with no fading or stains so far. Fit is spot-on for me (I took my normal 10.5 and it’s perfect—plenty of toe room, secure midfoot, and no heel slip). The mesh breathes really well, and the Charged Cushioning gives a nice balance of softness and energy return. I use these for runs (3-7 miles), gym workouts, and a ton of daily walking, and they feel comfortable from morning until I take them off at night. Three months and roughly 300 miles in, there’s barely any wear on the outsole and the upper still looks clean. They’ve honestly outlasted some shoes I paid twice as much for. Traction is solid on pavement, treadmill, and gym floors. At this point, everything else in my rotation is collecting dust. I liked them enough that I already bought a second pair to have on standby. If you’re looking for a versatile, comfortable daily trainer that doesn’t cost a fortune, these are hard to beat. Highly recommend.

I have literally searched years for comfortable shoes for my big feet and I finally found them!
Size: 15 X-Wide
Color: (002) Black/Black/Black
I have a size 15 extra wide foot it's always been a real problem to find shoes that fit properly. But these Under armor shoes are fantastic! They're roomy and comfortable and make walking enjoyable and fun again! The extra wide plus my proper shoe size it's very difficult to find size 15s and I was so happy and pleased to see that that size was indeed offered in the wide size! I love the styling of the shoe and they're really well made. There's just the right amount of padding and cushion so they're not squishy but they're not hard either. I like the arch supports, they're quite comfortable. The soles of the shoes seems sturdy and strong with a really good gripping pattern on the bottom. The shoes feel light on your feet and don't weigh you down. I'm going to order me at least one more pair of these right away so I have one as a spare. I highly recommend these shoes!

well built, comfortable, sturdy, soft, breathable, etc.
Size: 7 X-Wide
Color: (102) White/Black/Black
The charged Asserts 9 lasted me for years. I used them everywhere. However, I had to change the insoles to ones from boots for a more sturdy feel. I bought these since i've had 2 years with last pair that were getting tiny rips in fabric mesh , but they're made so sturdy that I felt they had more to go, so well constructed. These shoes feel just as good as the older line, and the insole they come with is great. I noticed they made a few modifications to the last line, like a different bottom design (outsole). I prefer the outsole on the 9’s, but this is just a personal preference. These shoes feel nice when I run, and the midsole is slightly thicker, which is a plus. Honestly, I love these shoes. I’ve bought other running shoes that I eventually throw away, always picking these back up every time. I also hate that other running shoes narrow the tip of the shoes and curve them upwards, these don't, who are these runners that want their toes tied up and squished? id give I higher rating if I could, amazing.
