I have boots that look just like that, except in blue and pink. I'm not sure if they are the same brand but they are the exact same style. I purchased them through pet edge. They've worked out well, though I don't use them much. They sometimes slip off but they do stay on better than other boots I've tried.

The only time I have really used them is on friends dogs actually. I keep them in my dogs hiking packs just in case but they've been on 12+ mile hikes fine, long walks in the snow fine, etc. I think their pads are tougher because of not using booties and regular walking...which makes it so their pads do not get torn up like I've seen on my friends' dogs....(one I used them on gets his main exercise chasing frisbees and running around on grass and the other does not get walked regularly at all). Maybe if you didn't use the boots as often her pads would be tougher? Just a thought. It just seems extreme that her pads would get so bad after such a short time in the snow. I think its a good idea for the hot cement though, when I walk my dogs in the summer its on dirt roads/trails so its not hot like that. Good luck!
