Last year I had a bit of a clear out, I had one 'good' pair of trainers, 1 'bad' pair of trainers, squash shoes, climbing shoes, winter walking boots, summer walking boots, an old pair of walking boots, approach shoes x2 pairs, mtb shoes, road shoes, touring type shoes

, a pair of rollerblades (

WTF!!), some spare approach shoes I use in the canoe and a pair of flippers, and 1 pair of 'shoes' which got used last year for work, a wedding, a christening, an interview and a funeral. MrsUser76 was amazed that I have a pair of activity shoes for every possible situation, but one pair of Asda £15 shoes for everything else
I have since up-graded to a pair of M&S Brogues, but I still have only one pair
