This morning I was back in my 12cm stilettos and as I was tottering about making breakfast I realised that something just wasn't right with the left boot. It's not just lack of practice or an inability to make the jump from 10cm to 12 cm, but something wrong with the heel itself. I took the boots off and gave the left boot a thorough examination. When I placed the sole flat on my table, so I could crouch down and see how the heel met the surface, it was obvious that the shank has twisted slightly. The heel is definitely a few degrees off vertical. It wasn't just my imagination or lack of talent. It's a relief in some way, I've been feeling frustrated, thinking how @mlroseplant and @higherheels have made such splendid progress while I seem to be getting nowhere. It's depressing too. This is my only pair of 12cm heels. I've been looking at the offerings of Fuss-Schuhe as recommended by @higherheels in another thread, and I like some of their boots very much, but alas the magazine world is not so brilliant at the moment and it might be a while before I can afford to buy myself some nice new 12cm stiletto boots. In the meantime I am going for immersive practice in my 10cm heels - hoping to maintain my abilities!
