Womens Bogs Outdoor Boots: Sturdy farm work boots for the harshest conditions. Bogs were first created for farmers in soggy Oregon, and these women's Classic Butterfly boots are here to prove it. They're 100% waterproof with a durable build and a burly nonslip outsole to navigate mucky stalls and muddy paddocks. 7mm Neo-Tech insulation keeps you warm and comfortable in subzero temperatures. Made with durable hand lasted rubber with a four way stretch inner bootie and a round toe.
