I have many other Five Ten products so when I went looking for a waterproof hiking shoe and saw these I was sold. I already knew my size and when they arrived the fit was great and I they seemed like a good design. I went hiking in japan during the rainy season and put about 60+ miles on them. They kept my feet dry,had great grip on rocks, mud, roots and had no break in period. When I got back from my hike I noticed that they were falling apart. Where they were coming apart was definitely a design flaw where the two different rubber types were glued together on the side of the heal so I returned them for a refund through Amazon. If they had not fallen apart I would have given them 5 stars
