How to remove cranks with 15mm bolts

I usually have no problem removing cranks. I use my 14mm socket wrench. I
have a bike that appears to have 15mm bolts. My 15mm socket won't fit in
there. Is there a special tool for these (I would guess early 80s) Sugino
cranks found on a Univega.

Sounds like your socket has a thicker wall than mine (12-point Sears
Craftsman), it works fine on all my 15mm-bolted Sugino cranks. Sugino
made a socket with a built-in T-bar, or there's the 15mm Park (or
Campagnolo) "peanut-butter wrench":

I'm guessing you could save a few $ with a trip to Sears for a single
15mm socket. Take your crank dustcap in and make sure the socket has a
smaller diameter.

Try a different brand of socket. Snap-On sockets and many
other brands fit, cheap ones don't. Or get a crank remover
with 14/15 sockets included. Or a trackie's "peanut butter"
wrench.

Usually a six point socket will do the trick. If you do buy sockets, make
sure they are smooth inside. Grind the outside down if you cannot get your
hands on a slim wall type. Otherwise a tubular spanner will do the job
(better to carry on the bike). You may refer to it as a pipe spanner (not
for pipes).

many special tools that are the 'old' standard of 15mm.

To be more specific, look for a premium quality 3/8" drive 6 point
socket. I've never found a 1/2" drive socket that will work here.

(Generally, higher quality sockets have thinner walls and better
clearance. Cheap sockets make up for lower quality steel by using more
of it.)

Then again, It might make more sense to borrow a suitable socket to
remove and discard the 15 mm bolts, then buy a pair of newer bolts that
use either 14 mm socket of 8 mm Allen wrenches. The bolts will likely
be cheaper than a suitable 15 mm socket.

Or get hold of a Dremel tool or other grinder and just sand down the
walls of the socket you have. Worked for me.

This has the added advantage of eliminating the need to have two tools
to get crank bolts out. Should the need arise to remove the crank
again later, no added time need be lost looking for the thinwall 15mm
wrench.

1/2" drive sockets always have thicker walls than 3/8" drive sockets.
Is your 15mm socket a 1/2" drive?
