My hubby was nice enough to give me a pair of brand new pair of Treadstone Field boots in size 8.5 xxw, but I've lost weight and now they are too big for me. My loss is your gain. They are brand new in the box, they've only been worn around the house for a couple hours. These are perfect for those people with bigger calves, because it's so hard to find boots that fit that aren't custom. The Treadstone site says these fit an 18 inch calf, but they have elastic on both sides, so it might even stretch further.
If anyone is interested in them I'm happy to take some pictures. I'm asking only $180.00 plus shipping. They boots are in BC, Canada but I go down to Washington every now and then so I can always bring these with me and then mail them from the US if that helps.
