I absolutely love these boots! I read many reviews & I agree with all the good ones.  Definitely go 1 size smaller, I'm normally 6/6.5, I ordered a 5 & they fit perfectly. As far as the ties falling, I've never had this happen after many wears, but I wear them well tied keeping the boot well closed, I don't tie them loosely maybe that is the difference? True that they may slip but I don't think any of these ugg type boots are meant to be actual snow boots.  I did however wear them after a snow storm & was fine walking on slush & some icy sidewalks, just being careful because pretty much any sole will slip on ice. They are fabulous for the price & what I especially love about them is that they are suede & wool but not shearling since I have an issue with baby animal hides.  The merino wool is warm & soft & i don't really have much of a shedding issue.. maybe just a few fibers here & there.  I ordered the chocolate ones & the color on this site is very accurate. I've gotten many compliments on them & I've never seen anything with ties like these so they are pretty unique. I am extremely happy with my purchase!
