This is my second pair of this brand of Croc, and its not because the first one wore out!  This is the most durable and sturdy pair of Croc's ever.  I am using these to hike with right now, yes, I said Hike in.  I just returned from a 55 mile hiking trip along the JMT (John Muir Trail) and finished with a climb to the top of Mt. Whitney (tallest in lower 48 states!) and I did the entire voyage with a 35 pound pack and a single pair of these Croc's.  They were amazing, no blisters even after hiking for 7-8 hours straight a day (10 miles average per day), the soles held up with no problems, and plenty warm.comfortable even in 30 degree temps (I wore socks) and 3 of my friends ended up with pretty bad blisters with expensive hiking boots.  Oh, also no problems rolling my ankle, these things really grip!  I am definitely more sure-footed with these than in those hard sole, super heavy hiking boots.  I highly recommend these, certainly everyday use and definitely for heavy outdoor use, I love them!!
