In my usual walk routine, I have short days and long days. Yesterday was a short day, meaning my walk was but a single mile (1.6 km). I chose to wear "real" high heels, just to up my game a little bit. Not all the way up to 12 cm, but close. Maybe 10.5 or 11, once you discount a little bit for my size 40. There is a big difference between that and my typical 8 to 10 cm walking shoes. If I ever get to the point where the high ones feel completely natural to walk in, that will be something. They weren't bad at all, I just never felt super at ease with them. The entire mile felt like, "Yes, you are wearing high heels."
