A bit on an offbeat question - I'm new to serious road cycling and have just bought myself my first fully-carbon bike and all the clothes and accessories that I need to get started, and I'm looking for a super lightweight pair of slip-on shoes that I might be able to carry around in my cycling top pouch? I don't know if such a thing exists.
If I went on a longer ride and wanted to stop off somewhere, it would nice to not have to clomp around in my Sidis

Something like this, but even lighter, that might fold up really easily? - 4oz a shoe.
