After about a week or so of not wearing heels again, last night was dog walking alone time again. So I got my jeans and heeled boots and went for a bit of a walk with the pup. Saw a gang of youths looking for trouble and decided that with or without heels I wanted no part of their evening and took evasive action. Still had a fair walk, and found my back pain even with the harder heels is lessened. It's either psychological or the change in posture.
This morning went for a very long walk with the dog, and wore my boots which are very comfortable considering they are cheapies. It was in daylight but saw hardly anyone around and don't think it would have mattered if I had, as the heels are pretty nondescript. Even after a long walk my feet were fine and my back didn't ache. Enjoyable way of both me and the pup getting out and doing what we want to.
