Sergio Grasso riding boots - I sell Sergio Grasso's riding boots. The model is Arezzo Young, a kid/teenage boot. Due to the removable second sole the boot covers two sizes. I had bought it as a training boot, but I don't get along with the cut as well as I thought. I have worn the boot about 5 times. There are small traces of use from the spurs. The bootleg size is MM, dimensions are shown on a picture. In my normal boots I have the measurements 49 (height) and 35 (girth).
