yeah, that's going to be a problem.
I got mine original Rom2 stolen (gym bag stolen).
Bought a used pair of Rom2's (practically new) for a great price,
BUT they only had the soft insoles in them, wanted those comp/hard ones again.
If you've never had a brand new pair, they come with two sets of insoles.
They competition ones are very hard plastic.
I researched it a bit and could never find anything....dead ends everywhere.
Let me know if you find anything.
