They look cool, seem to be made with good material and probably would keep your feet very warm. Ok, that's where the good ends.
These things are HUUUGGEEE. I opened the box and thought they accidentally shipped me 15s instead of 11s. This is the bulkiest, heaviest boot I've ever seen. Also I have high arches and my foot really wouldn't fit into them, so if you have flat feet or low arches then they would probably fit just fine. On a side note, they are not as orange as they look in the picture, more like if you mixed orange with a salmon type color.
I would recommend these to anyone looking to walk on the surface of the moon.
