Fidelio leather heeled slip-ons

Have to admit I'd never heard of this brand but I've made a nice discovery! These are quite lovely black leather slip-ons with a nice manageable 2" heel. Leather lining. Velcro closures on top of foot and at toe for perfect fit. Size 40; I'll list as 9. I was going to say 'in excellent condition'; the only sign of wear is inside the shoe (see last photos). However, I have just this second noticed.......is the insole missing?? I was trying to figure out those 2 little bumps at the back of the heel (last photo; you don't feel them as you walk) and the cotton bottom. Sigh. Anyway, they're lovely shoes but the price reflects this newly-discovered issue!
