Modifying Hiking Boots to get a snugger heel fit
So, I have a pretty narrow heel, mostly on my right foot.
I've been having a time finding hiking boots that fit snuggly (seems that everybody in the world has fat-ass heels).
I hit up every store in the SF Bay Area that "specializes" in hiking boots and ended up with some Asolos that fit great on the left foot, but still slip a bit on the right heel pocket.
Does anybody know if you can get extra foam or cushioning inserted into the heel pocket of your hiking boots to tighten that area up a bit?
Last time I had this problem (1980's Sportiva Muir Trail boots...they're in near-mint condition and for sale, btw), Marmot Mountain works "solution" was "Just wear thicker socks." Needless to say, that didn't work and I ended up with sick and thick blisters out in the Desolation Wilderness.
So, can you mod a hiking boot or are there shops/cobblers who will insert/add extra padding to the heel area?
Or am I just doomed to get blisters?
Also, if anybody knows of a boot that is tailored to skinny feeted people (although the problem with that would be the ability to try them on).
Thanks!
