I'm sad to say that I returned these yesterday. After reading other reviews about sizing I ordered a size smaller than what I normally wear. They were a bit snug and I would have been fine with my usual size. They were also tight around my calves and I had to roll them down which created a strange bunching of material around my ankle. I was looking for a boot with an aggressive tread which, on this boot, was virtually non- existent. On the plus side, the sole of the boot is extremely comfortable. It felt like walking on air. All- in- all, I probably would have loved these boots if the opening of the boot was larger and fit more loosely around my calf and if there was more tread. I might order a different pair that are cut lower if I can find some that have more grip on the sole.
