lime green Crocs
 

The foam sole on some of these galaxy Crocs might wear out quickly. Additionally, some people find that the textured rubber on the sole of these shoes is too rough for use in water. This isn't a problem if you're just hiking on a relatively smooth, well-maintained trail.

However, if you're on a stream, a lake, or other slippery surface, you might get some trouble. You could also slip and hurt yourself. Also, Crocs can be prone to slipping on slick rocks.
