I have 6

1 x road shoes(specialized)
1 x cheap exustar shoes that I use for lunchtime spin classes at the gym and keep in my locker
1 x didora touring shoes that are just a smidge small but I wear on my commute
1 x lake touring shoes that I use on my cycling holidays
1 x shimano sandals
1 x old road shoes (shimano) - I've put spd cleats on them have kept them on the basis that I'll use them on the spin bike at home - but I've been going at the gym so don't use it much

Put this in a context that normally I am so not a shoe person - I have two pairs of dress work shoes - one I keep at work to change into, one I keep at home for when I am travelling for work. I have four pairs of casual shoes (a pair of old running shoes, a pair of doc martens, jandals (flip flops) and a pair of crocs. Throw in a couple of pairs of running and gym shoes and the maths says more than a third of my total shoe collection is cycling shoes
