Absolutely love these rain boots! I have large calves and was worried that they would be too snug, but they fit perfectly. They are also comfortable for everyday activity. I wore mine with thin socks, and I did not experience any "rubbing" that could lead to blistering. The foot area is fairly wide, so I credit that for the comfort. Sadly, both days I wore these boots the rain never presented itself, but I have no reason to doubt that the boots will keep my feet dry during a downpour. The boots did receive several compliments- they are just so cute! As for the delivery, The boots arrived the last day within the estimated delivery dates.
