Regardless of the lining you choose, keep in mind that even the best winter boots can’t work miracles if you’re standing still in -25 °C weather.
Man-made: Generally made of polyester, or felt made to look like wool.
Wool: Wool lining is woven onto a membrane. It is widely used because of its excellent value for cost.
Shearling: In this case, all of the animal’s hide is used—both the leather and fleece—which makes for very warm boots. This lining is the most expensive, but the price is justified, especially when made locally.

Boots with a flexible sole are more comfortable in the long run, especially if you do a lot of walking. You’ll also want to make sure they are skid-proof. Some boots even have integrated cleats, which you can use when needed. The thickness of the sole is also an indicator of how warm a boot is. The thinner the sole, the closer your foot is to the snow!
