The lunar overboot was designed to give the crewmen
thermal and abrasion protection, as well as extra traction
in the slippery lunar dust.  Abrasion protection was provided
by the upper layer of Chromel R.
It was pulled on like a slipper
over the PGA boots.  The design stayed the same
throughout the Apollo lunar landing missions.
Lunar Extravehicular Gloves

covering, and silicone finger tips.  The 2nd photos shows the wrist
adjustment strap.  The far right photo shows how the
cuff checklist was attached to the glove.

Chromel R

Note - I have tried to find some more detailed information on
this material, to no avail.  If anyone has any good
info, please e-mail me.  Thanks!
Made of stainless steel fibers, Chromel R was one of the wonder materials of project Apollo.  It covered the backs, boots, and gloves of the extravehicular crewmen.

The Apollo 11 crew practices CM ingress.
Note the large patch of Chromel R on the
back of Buzz Aldrin's suit.  That patch was to prevent
abrasion of the PGA by the PLSS.


Life size closeup of Chromel R.  You can plainly
see the metallic nature of the material.
It provided excellent abrasion protection,
but was very expensive to produce.
