Let me start by saying that everyone that says these run big is understating the issue. These things are enormous. I wear a  US men's 12, and a Newport in 11.5. I ordered the 11 and had an inch of space at the toes. The size 10 fits much better but still has about one centimeter of toe gap. There are no half sizes. The straps fit securely and are very simple to fasten with one hand. The mesh is comfortable but the stitching around the fifth toe has a gap in it that chafes. When the shoes are wet the color is darker, so the espresso brown is black when soaked. The actual stitching work is well done and strongly secures the mesh top to the sandal.

 The soles are very thick, which was the main reason I chose these. I kayak and more often than I like, find myself walking on oysters and other unpleasant features. The grip of the texture is sufficient, the sandal does not shift when walking in water, and the soles drain sand and mud quickly without needing to be removed. They are also very light. The sharp rise in the center of the arch painfully pinches the first joint of my tarsal. It was swollen after a few hours. These are definitely not designed for hiking.

So based on all of these caveats I find it difficult to recommend these sandals to people new to Crocs like I am. I have flat feet and they are clearly not meant for me. They perform well as water protection or wading shoes but are a light addition rather than a daily wear. I will not be purchasing these again, but for $19 it's difficult to find a shoe with a thicker sole unless you grab rubber fisherman boots. They don't even approach the quality of my old leather Keen's, but the sea has not been kind to them over the years.
