The CabezaW boots look nice, but the leather is nothing special.  They are more wide calfed than many "wide calf" boots, but the circumfrence on the 8.5 is only about 16.5" inches.  The zipped farther over my muscular calf than most, but I still had to return them.  According to a local cobbler, leather shafts cannot be stretch more than 0.5."
