I'm looking at getting these, my first barefoot style shoes.
Size 12. I take a broad size 12 or a normal 13. 12 is "cosy" 13
is "roomy".  Any experience on the sizings of these? I want to
take the 12, but I don't really want to return them.  How do
these hold up in wet weather, I live in Glasgow (Wet West of
Scotland) during winter.
