Make sure to get a window seat, the footwell is a good deal larger than the middle seats. Bulkhead rows more so than regular window seats.
I have posted a similar picture before, but the window side footwell is not that small.
There is space under the footwell to have your shoes without them being squeezed by the reclining seat. Nothing more than shoes.
Things don't fall down between the window and the seat, but yes there is an trough there.
I am not trying to say it is a great seat, it is not. But it is probably not an entire disaster either. For the original intention of intra Asia flighs it was quite adequate for most. Problem is that it is now quite often beyond intra Asia.
