From a theoretical point of view, there are some possible
methods to take water out of a fabric object, such as a shoe: -
"Replacing" the water for another, faster drying liquid and
letting it evaporate; - Squeezing the water out directly by
compression and twisting (not usually adviseable); - "Force
field" like gravity and centrifugation; - Capilary action (which
is what the newspaper does); - Thermal action (sun, heater); -
Wind action (free-air, fan). The last two increase the rate of
evaporation, the first by increasing the internal energy of
water, the later by reducing the relative humidity of the air
layer close to the fabric. Then (always theoretically) one
possible way to dry a shoe quickly would be to force-circulate
warm, dry air inside a newspaper filled shoe that has been
previously centrifugated/squeezed after being rinsed in warm
water with a bit of alchohol. The problem that still persists is
how to actually implement this air heating and circulation
without a complicated device or combination
