Sandals ?
I have an older version of the same shoes you do but they don't feel hot to me when I do wear them. The ones I own have a mesh upper like a running shoe. They breathe pretty well.
Sometimes when the shoes I'm wearing are new and haven't been broken in or if they are too tight, they will feel hot, but it might be more general discomfort.
Otherwise, other parts of my body will get uncomfortably warm before my feet do. In the winter they are the ones that will be cold before anything else. This somewhat unique to cycling. My feet will stay pretty warm while I'm running.
