i was unaware how comfy and WARM these could be!  first muck boots i SO WISH i had purchased a pair years ago.....they are comfortable and fit my bunion feet great!!!....and i am SO easily cold my feet are so picky about fit.  and didn't think any boot but my sherling mukluk fitflops could keep me comfy and warm...but they aren't the best in piles of sloppy snow and manure...too short and NOT waterproof.  but THESE i can go from puddle to snow to manure pile and just pressure spray them off and somehow they keep my feet warm if not toasty warm and i'm SO impressed.  it was around 4 degrees F a week or so ago and i was outside most of the night (calving season) and i don't remember thinking about how cold my feet were....now i just have to find gloves that do the same for my poor cold fingers/hands!!  do they have Muck gloves??  hehehe.  SALUD!
