I ordered these in the color grey which I can described as a true smokey grey.  It is a great neutral.  My regular shoe size is 5.5MB. Sometimes in boots I have to size up to 6MB, but with this boots I ordered the 5MB and they fit me perfectly.  I have room in my toes and although they are a little bit tight around my calf muscle it is not uncomfortable.  Since they are rubber, I just stretched them out a bit at the top of the boot shaft at the highest part of the calf to loosen them up.  It made them more comfortable.  I would reorder this again.  Great buy!  Also, they are lined with a thin fleece and come with an insert sole that can be optionally removed.  They were delivered today and it happens to be rainning in my area, so I tried them out.  They are comfortable and do not need a break in period.  Also, they have great sole traction which reassures me that I do not have to worry about slipping. Additionally, they kept my feet warm and dry.
