I've been sent a mat covered in hard, sharp plastic spikes. Can I bear to stand tiptoe on it for 4+ minutes, changing position every 30 seconds or so to give you a perfect view of my tormented feet as I make myself stay on tiptoe, driving the spikes further and further into the soft skin of my highly arched feet? And when I show you the marks on the bottoms of my feet, will you feel sorry for me? Or would you like to see more?
