Can’t help with the smell, but switch the newspaper out a few times. 1.5 days of damp paper inside the shoe is bad. In fact, once the paper stops absorbing much, say after an hour, it’s probably better to stop stuffing it and let air circulate inside and out.
If it’s sunny outside, they might dry faster there. In the fall I dry my cx shoes on the forced-air heat vents. Since I discovered the insole comes out (duh, stupid me) I always remove that for the drying process as water can easily pool under it.
