"For the first year of the COVID-19 pandemic (beginning in mid-March of 2020), U.S. residents experienced substantially reduced geographic mobility, either due to policy restrictions, job loss, or the choice to limit contact with others in order to reduce the risk of infection. Additionally, nearly 25% of the adult population reported regularly working from home. Researchers wondered whether this notable change in mobility combined with fewer opportunities for social contact would lead to fewer high heel-related injuries."
"...The researchers estimated that from 2016 to 2020, there were over 70,000 heel-related injuries treated in emergency departments — about 14,000 per year. For 2020, this number dropped to approximately 6,300. The shoe-injury drop occurred after March 15; for January through March 15 of 2020, the rate of heel-related injury visits looked similar to previous years."
