Overland winter boots. They are completely natural fibers and materials all throughout the boot. The bottom features 'ice grip' (and it really works) i paid $379 for these. This design is no longer sold. They have lots of life left and hardly any sign of wear. My dog had bit the top of one of them and will be reflected in the price. Its hardly noticeable when wearing. These boots are narrowish they are a size womens 8 but would fit best on a 7 or 7.5. Overland is known for good natural products that last a lifetime!
