+1 B17 narrow here too, with laces

... It's definitely comfortable to me although still hard as a rock after 2000+ km, is it supposed to become softer? when? Ive been applying the proofhide every now and then.
It should
NEVER get softer! I'm beginning to think that is a popular misconception about the Brooks saddles ... that they soften up at some point.
I've got 35,000 kms on my saddle, and it has not become any softer than the day I got it ... thank goodness!! If it got softer, I might as well be riding gel.
However, what these saddles do is
break in. They develop divot and indents ... they reshape to fit your butt. If you've ridden for 2000 miles already, don't you have the start of the divots yet?
Keep riding it, and it will one day look something like mine!!
