Vince Camuto Leather Studded Riding Boots

Love these boots! But the calf area doesn’t have any give and I can’t zip them up completely. They are about 12inches in diameter 6.5 across. The soles are roomy and comfortable. All leather with brass studs and a zipper on the inside of the boot. I wear a size 7 and these fit perfectly but are labeled as a 7.5 B.
