Find the one called FOOT MARCHES.
Go to Appendix C.
Page 109:
"b. Proper lacing of boots not only prevents blisters but also
prevents improper blood flow in the foot. Laces can assume a
seesaw action, which can produce along blister across the instep.
To prevent blistering, lacing over the instep can be avoided. If
possible, broad laces should be used and an extra pair should be
carried."
