How to keep feet warm in the dbb?

[Guest guest]

's in the dbb 23/7 for the next two months. It's getting very

cold here in Maine, tomorrow morning it's supposed to be in the

single digits. Every time I take out into the cold his feet

turn into ice cubes in the open-toed shoes. I can't put anything over

his feet with the dbb on, except a blanket while he's in the car.

Does anyone have any ideas on how to keep his feet warm when we're

outside?

Thanks,
