No idea. Maybe not safe due to batteries. However, many, many people have had to wear casts, orthopedic boots with hardware and straps, and/or have had metal supports protruding from their skin as a result of surgeries and accidents, and they somehow, some way, found a way to adjust because the inconvenience was in their own best interest. Count me in this as having had several years of experience. Workarounds I can think of for taking baths or showers with large structures like casts covering one’s entire foot and leg include trash bags in the old days, cast and boot covers in more-recent times, and then, of course, perhaps the Seal shoe covers she and her sister sell. In terms of irritations caused by the metal such as that protruding from the skin—not just over it—, or over the ankle, foot, or leg, clean cotton or jersey such as from T-shirts, gauze, and any number of items have worked for many including myself. Is wearing such a device, whether related to a court-permitted item to keep one outside of a jail cell—something with which I have no experience, thankfully—or to try to save one’s ankle, foot, or leg fun? My experience with the latter is not at all. However, given the alternative, I at least was extremely grateful to technology that allowed me the opportunity to try to heal and live my life as normally as possible under the circumstances. So what if it took years? It was my best option, a condition that seems to me likely to apply to a person avoiding a jail cell thanks to the technological marvel of an electronic ankle monitor. When I think of what people now and over time have had to endure—and I am NOT including my experiences because in the long run and even for those years, I was so very lucky to have survived and there was and is no room for anything except immense gratitude at my good fortune—these complaints seem self-centered, clueless, and an insult to what others such as Jennifer have endured even without having been arrested. MOO.
