well i think i would only use shoe laces if there was some confusion.. normally i'd just call them laces..

and there are lots of possiblities for confusion --i knit lace!, so i have a collection of lace things, or laces.
but when i suggested some month ago that knitters take scraps of sock yarn and use a knob knitter (AKA a spool knitter, and various other names--i mean the kind of tool that makes ropes or reins, and to use them as laces in shoes or sneakers, (trainers) everyone knew i meant shoelaces and not some sort of exoitc lace covers for their footwear!

so i for 1 have replaced lachet with laces
