I have some 661's in pretty good nick, currently residing with Miss Socks - that I'm willing to let go for a song if anyone's interested. Size 43. They're the 2009 ones I think, I've used them about 3-4 times and I don't think Socks has used them at all. £15 if anyone wants them PM me. You'd have to collect them from The house of socks in East London somewhere.
Still have them? What colour are they?
