I also think I'm probably late to this little tidbit of information but after struggling with inflatable boot shapers that were far too large and looking at a wine bottle that was about to be relegated to the recycle bag I finally realised that I could use it to keep my boots upright and protected! You can also use rolled up magazines but since I rarely splurge on those any more that wasn't as handy an option.
The boots just flopping around (vintage Clarks from All Dressed Up in Chipping Norton)
The wine bottles--if you haven't tried the Chocolate Ruby chocolate infused wine from M&S you are missing out on on some deliciousness
My main problem is that I don't drink enough wine to have enough bottles for all my boots...surely that can't mean I own too many pairs!!!! I suppose I could go raid the neighbours' bins on the next recycle day but I catch enough eye-rolling with my Americanisms as it is.
*Obviously I mean footwear rather than the trunk (boot) of a car--related, I managed to say boot rather than trunk in a conversation today.
