I purchased 2 pairs of Therma boots last year for my daughter and myself. We are both delighted with these boots. I decided to buy another pair and this time chose the Version 2. They are harder to get on as the tag on the back is too small to put my finger in to assist in pulling the boot on.

So I have skeptical about these boots from the day I first see them advertised But though ok lets give them ago as I need a dry pair of boots for dog walks On 1st receiving the boots look very nice and I love the concept but the quality a little below what I would expect for this price boot The fur lining is very thin and the sol is also on the thin side they are comfatable but would be happier if they were more cushioned and had a thicker sol they grip well on normal ground and wet grass ...

As a Professional Dog Walker of 13yrs I've gone through my fair share of footwear. I have to say I was dubious when ordering these boots but I have to say it's the best decision I've ever made. I received them just before Christmas and started to use then in the New Year they are so comfortable and keep my feet warm and dry all day long in the snow, I've even tested them on ice and didn't slip once. Would definitely recommend to other dog walkers 5*
