Blisters are one way in which the body reacts to damaging friction.

Rather than wait to develop an unpleasant, painful blister, today’s invention is a stick-on synthetic blister, designed to provide the same level of skin protection but without the searing pain and infection risk.

This would consist of a thin, durable, flexible envelope containing a bio-compatible lubricant.

One side of this blister would have an adhesive patch which would allow it to be applied before wearing new boots on a long walk, for example.
