I bought a pair of these boots last year and from the off they fitted like a glove, were hardy in mud and rain and light enough to wear all day. Then, the night before last after a particularly muddy dog walk I left them on the doormat, meaning to bring them in later. However, I forgot. The next morning, only one boot was on the doormat. I was convinced my son was playing a practical joke but then our clever dog started playing with the torn-off tag from the top of the boot and still no sight of the boot! Yes, it seems that a midnight visitor acquired one of my boots, perhaps for some mice to sleep in (and now I'm getting carried away!). So, without delay, and because I loved the boots so much I got straight on to Amazon yesterday afternoon and ordered a new, identical pair straight away (having to fork out twice is currently shoved to the back of my mind - I just need comfy boots). I have just returned home at 1pm to find my new, shiny boots ready for me to wear for the weekend of muddy dog walks. Out of the box, they are just as comfortable. The moral of the story - remember to bring your boots in off the door mat before you head up to bed. And thank you Amazon - the speed of your delivery is second-to-none.
