Is this boot warm enough for winter?

The faux fur lining traps heat around the foot, which is enough for cold commutes and light snow. For long stretches outdoors in deep cold, a boot with more insulation is a better fit.

Does it keep feet dry in slush?

The outsole is water resistant, so wet sidewalks and light snow are fine. It is not a fully waterproof boot, so standing water or heavy wet snow can get through over time.

How tall is the shaft?

The shaft measures 6.25 inches, covering the ankle. That leaves room for tucking in jeans or leggings.

Why does it have both laces and a zipper?

The zipper lets you slide the boot on without untying, and the laces adjust the fit around the ankle. You can set the laces once and use the zipper day to day.

Is it good for ice and packed snow?

It handles light snow and wet pavement, but the outsole is not a deep lugged winter tread. For icy paths, look for a boot with aggressive traction or add traction cleats.
