Even if you take the right precautions friction between your shoes and your skin can lead to blisters and other painful irritants.
Although one can measure static friction coefficients , most of the friction studies on skin have, for simplicity, dealt with dynamic friction coefficients wherein the two surfaces move at a relative constant velocity.

Those marks mean the top layers of skin damaged by last summer's shoe friction are still healing, says Deborah S Sarnoff, a NYC cosmetic dermatologist.

In science:

It is hard to judge the importance of the discrepancy between −0.34 and −0.50 for the scaling of the skin-friction coefficient, in particular because the last three data points around Re ≈ 104 show a steeper dependence than −0.34, see figure 22d of Sun et al. (2008).
