These flip flops are incredibly comfortable to wear due to the spongy 'yoga mat' sole.  The white upper stays much cleaner than expected - the thong between the toes is made of a fabric and that grays faster and requires separate care to remain as white.  Over long distances (miles) these flip flops remain comfortable but do rub a bit on the bottom of the foot pad leaving the beginnings of blisters.  The major drawback to these shoes are that they become incredibly slippery when wet to the point that it was difficult to keep my foot in the shoe while going down stairs in a rain storm.  In addition to the slippery wet surface, the sole of the shoe 'bubbles' when wet - literally little white foamy bubbles come up from between the toes at the thong when walking in them wet.  So they're fantastic when its dry out and you're not going for much distance.
