Is the Sorel Ankeny II Mid actually waterproof?

Yes. Sorel lists it as waterproof, with a synthetic suede upper and textile lining. It handles rain and slush; it is not a rubber boot for standing water.

How warm is the 100g insulation?

It is a light insulation rating, suited to cool days and light snow. For sustained sub-freezing temperatures, a heavier insulated boot is a better choice.

Some owners report a snug fit and suggest going up half a size, especially for thick socks. If you are between sizes, sizing up is the safer call.

Can I wear it for hiking?

It is listed under hiking, but it is a casual winter boot with a 1 1/4-inch heel. It works for light trails and city walks, not rough or steep terrain.

One pair of boots. Laces come fitted; no extra insoles or care kit are included.

How does it compare with the original Ankeny?

The Ankeny II Mid adds a mid-height shaft and a toe bumper over the low original. Both share the waterproof upper and rubber outsole; the II Mid gives more ankle coverage.
