I was looking for the perfect muckboot: waterproof, comfortable, warm, and indestructible.  This is that boot.  The construction is bomb-proof.  The neoprene on the leg keeps the boot from cutting into your shin, and the boot fits almost more slipper-like than a boot.  My foot size at 10.5 fits the 11 perfectly with thicker socks, but even with thinner ones, the inside of the boot is so comfortable that any slippage is not a problem even when trekking after kids through creeks.  The handles on the sides make it easy to slip the boot on, though it certainly brings the waterproof level down a few inches due to the hole.  Not sure if I should have gone for the high rise to really tromp around in deeper water, but then I should probably be using waders anyway!  For its comfort, durability, and waterproof characteristics, this boot was well worth the money.
