Love them!
Size: 10, Color: Enamel Blue/White/Illusion Green
I love these shoes! Lightweight. Got a 10. True to size. My feet are a bit wide, and these are comfortable. I ordered another pair! Compared to shoe store prices, this was a deal.

Sturdy with Disappointing Details
Size: 9.5, Color: (001) Black/Summit White/Castlerock
They seem to be extremely comfortable, but I do worry about the quality in the long run. I wore these shoes one day indoors for 4 hours of kitchen work. The Under Armour logo is already almost gone from the inside of the shoe. I had a previous generation of the same shoe last several years with almost no visual quality decline. I hope this is not an indication of a cheap redesign that will fail in 6 months....... I might come back to update if there are major developments.
