In reply to dinodinosaur:
Not see Miura laces in shops for ages. Fortunately I bought two pairs at the same time. Forward planning.
As another poster says maybe try online. Rock + Run sell them.
FYI: You'll probably know the 'laces' are lined and quite comfortable. Mine stretched slightly which was great for my feet.
The 'VS' despite the same name is Velco and unlined and mine didn't stretch. Ouch! More of a drop toe too which I found uncomfortable.
Depends on your foot shape I guess.
Hope some of this helps. See an earlier Thread by I think ChrisBrooke.
