About Walking Sandals:
Walking Sandals are sandals designed to provide comfort and support during short or long distance walks or during all-day city touring. Many Walking Sandals have technical features found in good athletic shoes like contoured, anatomic footbeds and cushioned, supportive midsoles that provide good motion control and stability. The interior of the straps is often lined with a padded material that helps prevent excess rubbing and blisters.
