I love Frye boots, so I'm giving them a good review. The fit well, are made well, and the heel height is very nice. Not flat but not too high either. The biggest thing to know is they are NOT GREY. They are brown with a cool/grey type of tint, but if you expect them to go with a heather grey top or pants they will definitely look brown. The color is basically a cooler blue-based brown rather than the standard yellow-warm based chocolate color. If you want something that is truly grey, you'll need to find a different boot. The boot color in the picture looks more grey than it is.
