Waterproofed, Thinsulate-Lined Black Boot. This stunning style comes with a sheepskin insole (warm in the winter and cool in the summer - Google sheepskin for its amazing properties) - Glove-soft leather lining - Dual-density TPU direct-injected sole - Factory waterproofer applied (regular reapplication necessary) - Round toe Sizes: 3 to 12 and half sizes 3.5 to 10.5 NB This boot has been over-sized to allow for the thick sheepskin footbed, and some customers are finding that their usual size is too large. If you're borderline, go down to the smaller size. Otherwise, stick with your usual size, but bear in mind that you might need to add an additional insole under the sheepskin one to lift your foot into a slightly shorter and narrower part of the boot For a lighter weight, sleeker boot theAll Terrain series is a good alternative.
