I just received my exchange pair today so read and heed my words! The description says that it runs large so order a size down, so I went for a size 7.  Ouch.  My toes went to the very end and even turned up in the left boot - nowhere to go. Please order this in your regular size and if you wear a 7 1/2, order the 8, def. not a 7!  This is such a unique pattern and I just love it. The heavy lugged sole is not going to let you slip and slide, and  it seems to be well constructed so I don't anticipate any leakage. Did I mention that the insole comes out? Brownie points in case you need a bit more room. I'm giving the Green Conga 4 stars today but I have yet to wear them, even inside the house. I'm pleased that they are not flimsy, because our terrain does not consist of sidewalks and paved drives. I'm going to love them, and thank you Amazon, for your easy exchange service.
