These are so amazingly comfortable, one barely feels them on one's feet. The next best thing to walking completely barefoot. I ordered a size up, as the original Zennor's, where I had my foot size of four, were, (not for myself anyway) not quite true to size. The width also was slightly narrower, so had to have the insole out to wear them on long walks.
With the Zennor two, the width is far better and the fit perfect in a five. My feet are so cool in these walking long distances, as in 10 miles+ The extra sole, being breathable, is a lovely bonus and great for such long walks; whereas the other inner sole, is nice when it is cooler, without compromising the width.
I will most definitely recommend these to people who like to hike and take long rambles. Even on rough terrain.
I love the blue colour, which I have. So,so light and so very comfortable.
