After 2 solid years of use, my last pair of Merrell boots, (at least 2-3 hours of walking every day, often more) it was time to replace them. The Norsehund Omega Mid Waterproof have faired very well so far. They were a little tight around the ankles to begin with (some chafing etc) but soon wore in. After two weeks of solid use, they've proven very sturdy throughout snow, rain and cold icy weather. Warm and comfortable with plenty of support for longer walks. As with all my other Merrell products, I'm very please and look forward to wearing them for years to come.
