When I was on my stint of being "non-married," if the ambient temperature was very high, I would put my shoes in the 'fridge to chill 'em down. That really made the process much quicker.
At Bruggen, with the 1950's "single wall" Mess accommodation blocks & window frames with cracks that you could see light through, when winter arrived, chilling the shoes down wasn't necessary! It was back to child-hood memories (only a fire place in the living room for years) & scraping ice off the windows in the winter mornings!
No luxury of mum / dad taxi service for me, I had a a 30 min walk to / from cadets; going there (Ryde, Isle of Wight) was easy, it was a slight up-hill then a long down hill. Took a bit longer (in hobnail boots!) on my way back.
