Capped at the knee.
The upper of these boots are faux-suede. The calf is soft, but has cushion in the lining to make sure they don't fall and add extra comfort. The boot is 19.5" from the heel to the top of the boot so it ends right above your knee. You can also fold them if you like them lower. The calf width is ~14". There is a zipper on the inside.
Heel height: 2.25"
