Is the wedge heel comfortable for a full evening?

The 3.75-inch wedge spreads weight across the heel rather than a thin point, so it is steadier than a stiletto. Most buyers rate it comfortable, though a wedge is heavier than a slim heel.

Will these fit wide calves?

Some buyers say the shaft runs tight around the calf. If you are between sizes or have a larger calf, size up.

What is the heel height?

The wedge heel is 3.75 inches high.

What color do they come in?

They are offered in Black Combo.

Are they true to size?

Buyers generally find them true to size, with the square toe giving some room up front. Those with wider calves may want to size up.

Our take on the Fashion Nova Sienna Knee High Boots

The Sienna is a knee-high boot with a square toe, a zipper detail on the shaft and a 3.75-inch wedge heel. The wedge gives height with more stability underfoot than a stiletto, and the square toe keeps it comfortable for wider feet. It suits shoppers who want a tall boot that reads dressy but can be worn all evening. Against slimmer-heeled knee-high boots, it trades a little elegance for steadier footing.
