The softness after a vinegar foot soak is real. It’s also misleading.
Long soaking swells the skin’s outer layer with water, which is the soft feeling. At the same time, the water and the acid knock out of place the lipids that hold that layer together and keep moisture in. When the feet dry, the swelling goes, but the lipids don’t move back. The skin ends up drier and weaker than before the soak.
People usually soak for one of two reasons. For fungus, vinegar isn’t an established treatment; getting it identified and using a real antifungal is. For hard, rough heels, a soak buys one smooth evening, while daily moisturizing on heels and soles does the lasting work. Between the toes should stay dry.
For people with diabetes, soaking of any kind is generally discouraged. Reduced feeling in the feet means the sting that signals “too much” may never come. If a podiatrist has prescribed vinegar for a specific wound, their instructions come first.
