You rolled your ankle once, and now you think about it every time you step on the court or the trail. So you try to tape it yourself: four strips, a pair of scissors, and a YouTube video on pause. Ten minutes later it's lumpy, and one corner is already lifting.
The usual options all have a catch. A brace feels bulky and won't fit in your cleats. Rigid athletic tape locks your ankle up. A roll of kinesiology tape means cutting and guessing every single time.
