I get so many compliments on these!  They're great for summer!  They are surprisingly supportive and can get super muddy and then just rise them off.  Great for hiking and going to the beach.  You sort of have to break them in, they're a little stiff at first but I recommend going a size down.  I usually wear women's 10N and I got the 9.  There is a little label on the inside that will fall off within the first ten uses because it's not as stretchy as the surrounding material but I didn't like it anyway so I was sort of glad it did.  I wore these ALL last summer and they're still holding up!  My boyfriend loved them so much we got him a pair, he's a men's 10.5 and we got him the size 11.
