Follow these simple steps;
1. Decide winter boots are uncomfortable.
2. Take them to Oxfam shop.
3. Interlude to enjoy warm fuzzy feeling that follows having done a (slightly) good deed.
4. Remember that the boots were quite useful for brief social occasions.
5. Return to Oxfam shop. Buy back the boots.
Simple, eh? ( as that meerkat would say, only I can't write the squeaky sound)
