Comfortable and the perfect fit

My first pair of Under Armour shoes and I have nothing bad to say about them. They fit well and are comfortable. My favorite so far.

Size 11 is short.
Size: 11, Color: (110) Summit White/Summit White/Khaki Base
Am in process of returning them. The sole was very comfortable, but the size 11 was short.
Arch support was good and appearance was fine. Disappointed that they are short.

I really like these shoes
Size: 9.5, Color: (023) Distant Gray/Bittersweet Pink/Boundless Blue
These shoes are cute with the different colors. The cushioning, for me, is great. I got them for a trip with a lot of walking and my feet, which normally hurt, didn’t ache at all. I feel they are true to size. The quality seems good. Despite all the walking I did, the shoes still look brand new. I am really pleased with this purchase.
