after I have tried several Viking variants me these boots convinced. Have a 39 and here I had to take a 40, then it fits with thicker socks very well. The insole is to take out and my orthotics even fit perfectly into it. Because of the small paragraph, it runs almost as in a normal boot, that one has in rubber boots not always! Very rugged outsole, good conclusion on the leg, that it is not "purely rains", even with vigorous calves good fit, pants can still comfortably tuck. I'm looking forward to rainy walks! :-)
