Our love for knee-high boots will never die, so we outfitted this pair with sneaky details to make it extra-wearable. The wedge heel takes the pressure off the balls of your feet, while the stretchy calf extends to fit the natural shape of your leg. Throw in the leather welting and genuine suede fabric, and you have one stunner of a boot. 2 1/4” heel. Suede Upper, balance Synthetic Materials. Heel Rest Technology. Extended Calf.
