Using driver and front passenger footwells for storage

[gatvol]

Sorry if covered elsewhere....

I am looking for 2x sizeable soft bags that would fit above the rear shelf and behind the Rear seats.
After parking up these would be transferred to the driver's and passenger footwells. These footwells are cavernous - they will take brompton folding bikes in their padded bags for example

Has anyone found good sized bags that fit nicely and make good use of the front footwells please?

Thank you

I use these sort of things:

One of my most useful is a 40L drybag which leaves home empty, and comes back with all the dirty clothes in it

You might find four (or more) smaller bags more flexible than two massive ones.
