Nice. Our solution is a shoe bucket. We have a large bin with a snap on lid that gets put outside upon arrival, it's only purpose is to store extra footwear. Everyone is allowed 1 pair of shoes out of the bin, all others are stored inside it.
On a week long trip it is not unusual for 4 Psuedo-Adults (I am a child at heart
) to have 12 pairs of shoes with us. There is no room to store all of them indoors, particularily when several of them belong to a teenage boy... Who wants that smell in the RV
