Not true to size
Size: 8, Color: (100) White/Pomegranate/Rush Red
The shoes are beautiful, same as the picture. Super comfortable and very lightweight, but wait to big, I’m a size 8 and bought a size 8 as usual, I never had any problem with the UA shoes before, this shoes are about 2 inches bigger on my feet. I will return them and order probably a size 6 & 7 to see which one fit better. That’s the only reason I’m not giving a 5 starts!!!!

Great fit, support and quality
Size: 6.5, Color: (101) White/White/Metallic Silver
I bought as a gift for my wife, she loves everything about them, the fit, support, and quality. These are to replace a pair of Under Armor shoes that served her well and lasted a long time.

Not a fashion statement, but the best for my feet
I’ve had these for a year & alternate between these & a pair of Nikes & they’re still in great shape. I tried just about every brand in my hunt for walking/light jogging sneakers, and for me, these were by far the most comfortable, even over $160 New Balances & expensive Diadora & ASICS…Adidas Ultraboost etc. Every foot is different - for me, different shoes press against the inner foot bone uncomfortably, and there’s no issue with that here. The sole is thick & cushiony which I find supportive, and my feet don’t feel overly compressed. There is a nice little bounce which each step. True to size. I’d recommend.
