The main reasons your legs itch when you walk are related to increased blood flow and nerve stimulation during exercise. When you walk, your heart rate rises, causing capillaries and arteries in your legs to expand to deliver more blood and oxygen to your muscles. This expansion can stimulate nearby nerve endings, which the brain interprets as an itch sensation. Additionally, exercise triggers the release of histamine, a chemical that causes blood vessels to expand and contributes to itchiness. Sensitive or dry skin, allergies to detergents or clothing materials, and sweat-induced irritation can also worsen the itching. This phenomenon, often called "runner's itch," is more common if you haven't exercised regularly for a while and usually subsides as your body adapts to regular exercise.

If the itching is accompanied by symptoms like hives, rash, difficulty breathing, or swelling, it could indicate an allergic reaction or a more serious condition requiring medical attention. Otherwise, maintaining a regular exercise routine, using mild detergents for sensitive skin, wearing moisture-wicking clothing, and moisturizing dry skin can help reduce itching.
