These worked great! Size is true to size for Boots (not nike or adidas sizing) I used them for a snow trip and did a bunch of walking,  hiking, etc in these and I have to say I was impressed on how it kept my feet dry while in the snow and rain.  The bottom surface has some grip but on slippery flat concrete it does slip a little if you are not careful. Not enough to minus a star though considering the awesome price of under $30! Plus I like how they looked like normal street sneakers so it matched in jeans and snow gear. Less stuff to pack on the trip! After 2 weeks of constant use, they still look great and still are waterproof.
FYI THEY DO NOT BREATHE (makes sense though) so when I wore them as regular street walking shoes in the city,  they got a bit warm in the toes. Not a negative, just an observation
