3. Discoloration (blue, purple, or pale feet)
A bluish or purple hue may indicate poor oxygen supply.

Pale or flat feet may indicate improved circulation.

4. Numbness or tingling

Restricted circulation can lead to tingling or numbness.

This may worsen with increased activity and improve with rest—a possible sign of peripheral arterial disease (PAD), often associated with heart disease.

5. Wounds or non-healing wounds
Poor circulation can prevent the body from healing even minor cuts.

Chronic ulcers or slow-healing wounds on the feet are a warning sign, especially in diabetics.

6. Pain when walking (limping)
Pain or cramps in the feet or calves when walking may indicate PAD.

It is a reliable indicator of future cardiovascular events, including heart attacks.
