i agree in theory completely with ham: best looking shoewear are boots or heavy looking shoes to keep balance. in my very beginning i only wore those kind.
no discussion: they look better then light shoes, snadals and for sure flips.
but in summer there are really a bit to hot, and concerning people: they were more wondering on heavy boots than on my kilt. i turned wearing whatever i liked in my kilt, even if it don t looks as good as my favotite heavy shoes.
at least we should not establish to much rules, as this would scare other poeple to wear teh kilt.
