Only not very warm.
I bought size 13, which is 47 here in the Netherlands, and my foot measures 30 cm exactly. Local stores here sell up to size 46 only and those don't fit very well. I have bought size 47 (13) and my first impression is they fit very well. The sole is sturdy and does not bend easily. Some find this positive, others not. The sole at the nose of the shoe does bend to some degree, so I am pleased. I will need to wear them a few days to get a better impression, but as it looks like this is a real good deal.
