I've been wearing zero or near-zero drop shoes every day for two months now. For a few years, I've had a very tight lower back and accompanying pain after standing relatively still or walking slowly (think concert or museum outing). Since going the minimal route, this has almost entirely disappeared.
However, last weekend I was doing a longer-mile day on rocky ground and didn't want to bruise up my feet, so I wore my New Balance Leadville 1210s (they have an 8mm drop). Now my lower back muscles are very tired and sore — I could barely jump rope today at the gym because the impact of each landing made me semi-seize.
Has anyone else experienced this sort of thing from a sudden increase in heel height?
