When these boots arrived, I was pleased that the cleat-like treads looked and felt just as "grippy" as they had appeared in the picture.  I have worn them in snow, feeling quite secure, but will probably use additional ice wear if "dreezing frizzle" rears its ugly head.  The loops on front and back, and the give of the back laced area makes them easy to put on--I can do it standing up without keeping the dog waiting to obey his call.  :-)  At first wearing, they seemed just a tad snug, but have stretched a bit in the couple two three weeks I've had them.  My thickest socks feel fine.  (I didn't up or down size.)  And, it was also as I suspected.  They are quite attractive, meeting my standards in this area as well, most of all lacking that clumpy feeling.  Warm?  Yes, indeed, and thanks for asking.
