For the rub, before it’s a blister.

Same hydrocolloid gel, different job. On a blister it cushions the skin, absorbs the fluid, and keeps the area moist so it heals without bursting. Stick one on the moment you feel a hot spot, and it stops the rub before the blister forms.

Pre-cut patches in the sizes that fit heels, toes, and the ball of the foot — or the roll tape, cut to fit the spots a fixed patch cannot. For breaking in new shoes, long walks, and anyone who has watched a good day get cut short by their feet.
