Probably my answer comes too late, since you already cut your footpockets, but with a friend of mine we fonnd a nice solution to cope with cold water. A solution that I think is worth sharing: we just cut the foremost part of a pair of 5mm socks, then we wear them not on our feet directly but ON TOP of the monofin footpocket, after inserting the foot, in such a way that the socks cover most of the footpockets, the feet, up to the ankles. This way very few water enters into the footpockets and the feet remain hot, even in cold water. Moreover, this also seals the feet and the soap you use to ease wearing the monofin (mine is so tight that I need soap even when wore barefoot) remains there longer.

I hope my description was clear enough and it could be of some use to others.
