These may not be scottish, but they sure do keep the
briars from attacking your legs. I just bought a pair and
found them to be very comfortable. The tall ones are
about 18 inched high. They are very soft, like a glove
for your feet. Also the "tongue" is sewed to the sides
all the way up, so it never falls to one side. You can get
them at Atlanta Cutlery. (Search for "boots")
