These are the 550 leather lined walnut brown. I have too many Blundstones and recently only wear the heeled ones so these don’t get any attention. I’ve only worn them a handful of times but managed to scuff the front up (reflected in the price) could probably spruce up with some shoe conditioning/shine. Structurally they are in great condition.Aussie size 6 I am a true US 9 and size 6 fits perfectly.
