Are these boots actually waterproof?

The upper is described as waterproof and oil-resistant, and buyers report dry feet in snow and slush. Waterproofing on any boot fades with wear, so treat the upper periodically.

How cold can I wear them?

The maker rates the 200g Thermolite-style insulation to -25F. That is a manufacturer claim; real comfort depends on socks, activity level and how long you are outside.

Are they good for hiking?

They work for light winter walks and trails. The ankle height and rubber outsole suit packed snow and slush, but they are not a mountaineering or deep-snow boot.

Do they run true to size?

The listing gives no fit guidance beyond the size. If you plan thick winter socks, consider whether you need extra room in the toe box.

What is the insulation made of?

The lining combines microfiber with a heat-reflective layer, plus 200g Thermolite-style synthetic insulation.

How do they compare with Sorel or Columbia winter boots?

They claim similar waterproofing and insulation at a lower build tier. The premium brands generally offer more refined construction and longer track records; these suit budget-focused buyers.
