Hmmm,
I think the only situation I can imagine where sandals would make sense:
is if they are a kind of specially made torture-sandal.
Such as with nails or tacks sticking upward from the insole or so.
Otherwise of course I'd expect to be barefoot, what sense would there be in putting anything on my feet.
And so I'd imagine myself something like the drawing for this scene,

The only way it could make sense for me not to be barefoot on the way out would be if there is some kind of convoluted religious/ritualistic reason or legalistic interpretation that stipulates my feet not being allowed to touch certain ground etc.
Though in that case I'd rather expect to be bound to the cross beforehand and carried around in some kind of ceremonial procession,
that also does show up in my imaginations sometimes...

Those different textures underneath my feet, that's something I imagine also,
being intensely aware of that.
(a bit like the sensation when you're blindfolded and led barefoot over some very different surfaces).
It would probably start with cobblestones, sometimes dry sometimes slippery.
The post of the cross I'm dragging behind me would be going 'tok... tok...' as I drag it other the stones.
Later there might be the arch of a bridge to cross,
maybe it is an old wooden one that is rough and splintery but warm from the sun while water rushes underneath.
Outside of the town now, cruder paths. Damp earth – then dry, rough roots, soft round pebbles or sharper gravel. Where it’s been shady since the last rains, soft mud squishing between the toes; where the sun has insisted, brittle dry flakes crumbling beneath my soles. Maybe there will be a small stream to cross.
Thinking of it situations like this show up in most of my scenarios I've posted
Yes that is when I know my walk is very near the end. that moment when I realize the pointy things pricking my soles are now not actually stones, but vertebrae and other fragments, remains of those sentenced before, and trying to cope with the realization that this is the fate intended for me as well...
