I came across a bag of slotted cleats, some for Detto Pietro, some for Duegi, a pair of Sidi's and a few unknown, unmarked pairs.
They can be seen on flickr at:
Prices for all are $15 shipped in the continental USA, any additional pair $10 (shipped in the same padded envelope.)
First come, first served. Email me off-list with what you would like and I'll let you know if it's still available and payment info.
