I tried on the 405 in standard brown the other day and I quite liked it. It looks quite reddish in tone, and went well with a dark pair of jeans. I was originally looking for a burgundy/oxblood boot but I think the 405 in standard brown will fit the bill.
I must say the chromexcel leather has a much nicer finish though - the standard brown has a wax coat (?) which doesn't show off as much of the natural leather luster. Wish they had the reddish brown color in chromexcel.
I also saw the natural chromexcel in person and man it looks beautiful. Almost a bit irridescent. If the 405's in standard (reddish) brown work out for me I will definitely pick up a pair of these
Funny thing is, until I tried on a pair of 405's I thought they looked pretty ugly based on the photos
. Trying them on though they seemed much nicer, and man they were comfortable.
