I have a pair of Orvis Henry's Fork wading boots that are about 3
years old. The felt is coming off of one of them. I really like the
boots other than that. Good foot/leg support.
Can anyone recommend how to fix (replace the felt) or have it
replaced?

Thanks in advance.

They sell kits in fly shops to replace the felt; I have used them and
they worked fine. Because I tend to walk on my boots as well as wade in
them the felt soles do go down fast.

You can't go wrong with the veteran advice you got but for what it's
worth--maybe a laugh--this is what I did just this week: I got a remnant
of something that resembles boat carpet and put two layers of it on top
of the old soles, which I of course first brushed clean, and then
slathered on ShoeGoo until I ran out of it, finishing up with waterproof
construction adhesive. I held everything together with package tape and
the next day trimmed my masterwork with one of those curved flooring
knives and refined with a grinder.

Now I haven't so much as dipped a toe in water, but the boots walk
great, look great, and like a duck--I think they'll take to water just
fine.
