Colin Campbell said:I suffer at times from "hot foot" - the soles of one or both feet feel
as if they're on fire. The most recent occurrence was at the Tour de
Palm Springs, where temps reached 81F. That was the first time in a
couple of years I've ridden over 100 miles. (I removed my shoes at one
rest stop around the 80 mile mark for 4 - 5 minutes, and that helped,
but the sensation returned later.)
I've read that as people age, the thickness of the padding on the soles
of their feet may get thinner, and this may lead to the "hot foot" feeling.
But I'm beginning to believe that my Sidi shoes are possibly somewhat to
blame. For one thing, my feet seldom feel cold on winter mornings, and
I used to have that feeling regularly a few years back when I would
commute to work in 35F - 40F temps. There haven't been any 35F mornings
this winter, but I've ridden at 38F to 40F a few times. I used to wear
double socks on those cold mornings; now, it's just standard cycling socks.
Are there other quality brands that are better ventilated? I may need
to have an alternative to the Sidis for the warmer months.
(VeloNews studied seven brands of carbon soled shoes in the recent
buyer's guide, but didn't rate the shoes for ventilation.)
Dear Colin,
Better shoe ventilation can't hurt, but you may be describing
progressive peripheral neuropathy, not actual heat.
I hope that's not the case, or that you just have less padding on your
paws, but . . .
A) The soles of your feet felt as if they were "on fire" at only 81F.
B) Removing your shoes for "a few minutes" helped.
C) You no longer feel real cold too well.
***
A) If your "burning" feet were just hot, they'd cool off in moments
when you took your shoes off, not minutes.
It's common for progressive peripheral neuropathy to give the
sensation of burning, freezing, and swelling. Your brain has to put
some interpretation on the false signals.
B) Taking your shoes off for relief that takes a few minutes (and
putting them back on a few minutes later for the same reason) is a
classic sign of progressive peripheral neuropathy--the slight change
in stimulation makes a difference in the annoying static coming from
the nerves in the feet. Velcro straps are darned helpful.
C) Failure to notice real cold (far more common than real heat) is
another classic sign. The failing nerves no longer transmit true
sensation, so numbness to real cold and real touch is the other side
of progressive peripheral neuropathy.

It's hard to realize that your feet are going numb when you can feel
them burning. Who bothers to test their toes for sensation?
A doctor will have you close your eyes while he touches your feet with
a very thin wire. He won't take long, won't go double-or-nothing, and
won't try again with a thicker wire. You can try it yourself if you
have a lovely assistant. (It's awfully hard to do on your own.)
The progress of the disease can be so slow that truly dim-witted
victims can take several years to figure out what's going on, even
with a family history.
Or so I hear. I'm still in denial. The silver lining is that my feet
no longer bother me on cold rides.
Cheers,
Carl Fogel
