I think I'm weird with my preferred fitting.
9 1/2 in Vans are too tight to walk a mile in.
8 1/2 Clark's fit and would stretch to comfort but I prefer 9 for everyday wear with medium hiking smart wool socks.
I don't really remember 81/2 in 1,000 miles but I'm sure they would fit ok but I can wear my 8 out hiking with thick socks and without much toe room I never have toe jam.
Does anyone share the similar preferences between brands?
