I bought these shoes because we were going to hike next to a river and we would be jumping on lakes and going through slippery rocks  and crossing creeks so everything we would carry needed to be able to get wet but also allow us to walk long distances withough getting all our feet blistered (Thus, flip flops were not an option).

These shoes did not only fit our needs perfectly but they have been one of the better purchases I have made in my whole life. They dry very fast, they are not heavy when you are swimming (you can swim through fast currents without problems), they protect you from rocks and they are not slippery. I have walked through very slippery surfaces with these shoes on (completely wet) without falling or slipping (I have three left feet so that's quite an accomplishment for me).

Their firmness and light weight make them a very good choice for hiking or walking or even running in tropical environments, where boots slow you down and are too hot. I prefer them to any other kind of sneakers, especially after my equally expensive Nike Shox literally dissintegrated on my feet in the middle of 5th Avenue under a drizzle (It was not even a proper rain and the sole just came out entirely and the shoes began to crumble as I walked!).

And yes, they are very easy to clean.
