Wanted: The large frames for sale thread 25" or 64cm what have you got?

Indeed, I'm a uk15 in converse, 14 for work shoes and have Shimano SPDs in 51 wide and 52 regular. I'd read that Shimano and Sidi sizes were comparable but they're not, it turns out. If anyone knows anyone with massive feet, or who likes wearing lots of socks I'll sell these for cheap!
