Try soaking it in warm water and letting it dry!!
When wet? Probably not exclusively from water. However, water and HEAT can absolutely shrink a leather belt, sometimes by several inches! If you were to wash your belt or otherwise get is sopping wet, and then leave it in the hot direct sun or throw it in a dryer, it may very well shrink.
You can shrink leather by putting it in boiling water for about 10... leather gloves stretch a lot
Shrink. Contract.
if leather gets wet or damp it can shrink, but it can also stretch when its wet; wet the inside of the shoe and wear it, it will stretch out
Use a leather cream/cleaner on it. Wetting the leather may make it shrink and ruin it.
No, the leather will begin to fade and flake off. It will also shrink considerably.
Well you really can't. Leather does not exactly shrink, particularly boots. If you get them wet, it will just ruin the leather. If your boots are too big you should exchange them for another pair or sell them on Ebay and purchase another pair.
Oil it.
