People expend a lot of effort in removing hair from their legs. I’m not sure why they do, but I notice that my running tights are effective shavers…at least where the material rubs the legs.
In the left diagram, a section through a runner’s calf is shown.
Ginger hair is left in the concavities of the calf muscle and the shin.
On the right, a pair of running tights is shown with extra, internal padding at these locations.
The natural running motion allows these to do a good job of smoothing anyone’s lower limbs.
