Poorly fitted and they don't breath.
Received my pair of Hobibear Birch 3.0 - Winter Barefoot Shoes. They look great. The grip on the sole is good and they are toasty warm, however the fit is tragic! The fit is like a loose welly. My feet slip around inside them. Going down hill my feet slide forward and my big toes hit the front. They may be waterproof but they are not breathable, so your feet soon get sweaty. I would not recommend them.
