I am a bit of a shoe collector too, as it happens I have just sorted through my wardrobe and bagged up about 20 pairs for the charity shop.
Currently I have 7 pairs of trainers, 3 pairs of sandals, a couple of pairs of pool shoes, 10 pairs of smart formal shoes for work, several pairs of boots, walking shoes, gardening shoes and of course my slippers.
Is that too many

Dont get me started on clothes, I must have at least 20 suits and 30 formal shirts, 30+ casual shirts and over 100 ties
