Yeah, or just file one. For size 48, I'd say spacing out the toe clip from the pedal is your best bet. The normal Zefal/Christophe L/xL is pretty much at the limit with 46.

BITD the standard thing was to tell people to size down at least 1/2 a size from their normal shoe for cycling, but that's when they were all leather and would stretch.

There's not many good choices for toe clip users these days. I almost got some Giros, but something about them kind of turned me off. I wish I would have kept one of my old pairs of Dettos or Duegis. While I plan on going back to clipless soon, I am riding my old PX10 for now. For the interim, I got some Chrome truks, which are not bad.
