I have them and in the exact same size. I would recommend them- they're very comfortable and look nice too. Mine fit well, but are a little tall and rub behind my knee, so if you are quite short like me that may be a problem until they break in and drop a bit
The quality seems excellent for the price. I have them for shows and also ride 3-4 times a week in the mountain horse high rider boots. The high riders are still going strong after 4 years, and I have no reason to expect the richmonds to be any different.
I have these exact boots. My right calf measures a 15 1/2, the left a 16 exactly. These boots fit BEAUTIFULLY, and the foot is SO comfortable. LOVE, love, love. I'm usually a 7 1/2 in a street shoe, and the 7 wide fits me perfectly.
