Have any of you tried the Knox 600? I really like both colorways. From all the models I tried, the 306 fit the best, but I can't wear Vulc shoes anymore. Most NB's feel a bit too narrow for me in the middle and at the heel. The 600 looks quiet narrow in the middle of the shoe but look good at the toes and at the heel. Haven't tried the 1010 yet and the 480 felt way too large the size US 7,5 I tried.
