Wore these only one day so far and I got many compliments on them.  It is just like walking on rubber, so it isn't the best in comfort but it is tolerable.  The laces seem sturdy and eyelets too.  Cleaning these is easy with just a damp cloth.
There is not real flannel or any other materiel lining inside besides rubber, but for the price you knew that already.  Unless you jump into a massive puddle, these keep your feet very well protected from the rain,,,not recommenced for a monsoon.  I love the red and black color and how unique they are.
