Keen Women's Gypsim Mid, size 7.5 with KEEN.DRY waterproof membrane. Similar product to this: http://www.keenfootwear.com/product/shoes/women/gypsum-mid, but from a few years ago. These are used boots, in fair condition. I used them for day hiking mostly on easy terrain, and I put about 50-75 miles on them over 8 months. The are still supportive and the waterproofing is excellent, but I purchased new ones because these are too wide at the toe for my feet. If they are a good fit for your feet, you can probably get another 200 miles of awesome hiking/backpacking out of them. $20 OBO, for pickup only at Stanford Eng. Quad or EV.
