It has been an especially wet spring in my region of the country, and taking the dog to the local park every day, where we trek a couple miles over fields and through woods, was making a mess of my old tennis shoes and my feet. I came back with my feet & socks covered in mud, and with shoes that had to be washed constantly, so they were never dry by the next day when I needed to wear them again."Duck Boots" was the obvious solution to this situation. I didn't want a cheap pair that would fall apart after a couple months -- I needed a pair that would stand up to daily wear. I wanted proven quality, which is why I went with Sperry.These are really good boots. I got the navy base with the navy nylon upper. I put gel inserts inside for more support because I found the inners a little hard for my middle-aged feet. I have worn these every day for about a week and a half, since they arrived, and I am very happy with them. I can tromp through the muckiest mud and the boggiest fields (you know dogs, the messier the spot, the more they want to go there) and my feet stay D-R-Y. Then I just hose off the boots when I get home. All is dry and clean for the next day's adventure at the park. Easy peasy.Solid quality boots. Good purchase.UPDATE: Nov. 2020: Been wearing these boots on dog walks and hikes in nearby state parks for nearly 18 months now, and they have held up beautifully. The laces are intact, no cracking around the soles, tread still good. Really happy with this purchase.
