I also have the Quiksilver Monkey Wrench 2 sandals. It seems like a cheaper approach was taken to the Monkey Wrench 3 sandals in comparison to the previous version. The soles are not as comfortable. The comfort is the biggest difference, as the previous version is softer and feels superior. The Monkey Wrench 3 is harder and less comfortable.<br /><br />Now, overall, they are what I would call &#34;ok&#34; flip flops, but I'm definitely bummed they aren't like their predecessor. I wish I could still get the Monkey Wrench 2 sandal in my size, because those were A+. These, well, are more of a C. I'm assuming Quiksilver tried to cut some costs with this version.  If you can find the Monkey Wrench 2 in your size, go with those rather than the Monkey Wrench 3.
