I wasn't sure I would like the Injinji socks but love wearing them.  The fit is perfect and so comfortable to wear.  I've worn them with tennis shoes,  regular shoes, even my sandels.  I found them a little hard to put on but once I did it a couple of times it became easier for me.  These are now my favorite socks!  I wear a size 6 shoe so I ordered the small.  You can get these in the blue, aqua and green.  I wish they had black in them as I wear a lot of black slacks.  I'm not sorry I ordered these socks, now I want more of them.  Try a pair!
